You still need a good bullet with a good nose profile and a hard enough alloy that won't distort but isn't too hard to be brittle. Lack of penetration is a function of the bullet, not the caliber.

That is true; bullet integrity as well as the heavy weight and high SD. I cast my bullets using various alloys, dependent upon the intended velocity.

Have you used your 270 grain load on elk or moose?

Nope. Never used them on brown bear or caribou either. As I said, I use an alloy appropriate to the velocity and count on the heavy weight and high SD of the bullet to completely penetrate the critter. Really, really tough to stop a heavy, well constructed .45 caliber bullet.

CraigC posted some gel testing in another thread for both .44 magnum and .45 Colt. The data presented did not tend to support the notion that ANY of the loads under discussion would shoot lengthwise through a horse unless it is a mini-pony. I don't know anything more about it than what was posted, but maybe Craig can let us know how the gel tests tend to perform relative to real life. I know for stuff like LE/SD hollowpoint testing for 9mm, .40, and .45, gel tests tend to show MORE penetration than what you would see in an actual assailant.

Hi Eldon,

In all fairness, the material Craig used is tougher than animal flesh, limiting penetration. As soon as the nose gets wiped off, penetration suffers greatly. I would however make a sizable wager that a 240 grain swc at 1,100 fps will not go lengthwise on a horse -- any horse.
 
I've posted this picture before but I thinks it's pertinent to the subject. The bullet was cast from an RCBS 44-250KT mould and weighed 258 grs. cast from ACWW. Loaded in a .44 Special it struck a buck at about 1050 fps in the left flank, traveled up through the body coming to rest under the skin ahead of the right shoulder.

Judging from the smear on the nose it struck a bone somewhere on the way. Pretty good penetration from what most handgunners would consider a "light" load.

Agreed, not trying to say they don't penetrate well, just trying to rein in some of the myths. If it doesn't go all the way through a deer diagonally, tough to imagine it or the original load going end-to-end on a 1000lb horse.

In the Box of Truth water jug testing, a RNFP 250 @900fps went through 5 water jugs and bounce off the 6th. That is similar to non-expanding 9mm,.40,.45, etc. The SWC at the same velocity went through 6 and penetrated the back of the box. Interesting to see the difference bullet shape can make.
 
I agree with Eldon. Not saying they don't penetrate well, but there is a huge difference between a whitetail and an animal as heavily constructed as a horse weighing in excess of 1,000 lbs. I have found also that bullets that do well in whitetail don't necessarily do well in mature boar where the bone construction is heavier and they have a gristle plate to contend with.
 
This is why I prefer LBT bullets to all else. The bullet on the left is a Keith SWC and the bullet on the right is an LBT WFN. The SWC still works, but I prefer the bigger wound channel provided by the bigger meplat.

I think it's safe to say the expectation of the original 45 Colt bullet penetrating the length of a horse is the result of internet propogation. If that truly was a requirement way back when, it'd be fascinating to read that/those documents.

Regarding the WFN style bullets, couldn't a person just use a full wadcutter which would have a full dieter meplat?

35W
 
I think the issue with a full wadcutter and even to some degree with the WFN which Max touched on is long range stability. There is a LFN design in the LBT lingo with a bit of a smaller meplat made for longer ranges. I think there is also a WLFN or something like that which is somewhere in between.

Given my abilities, I'm sure I'd be fine with a WFN and probably even a wadcutter range-wise.
 
I'd like to break this down and get away from the mythical crap about killing horses. Firstly, no one is arguing that a standard 250-270gr SWC at 900-1200fps doesn't work. It does and it works with boring regularity. However, killing deer and 150lb wild hogs is not the same as killing elk, moose, buffalo or the great bears. Sure, it might work fine in any given situation and it might not. The point being, there ARE better tools for the job of dispatching bigger critters. If the heavyweight LBT's were not better suited to some applications, we would not have or need them. What people don't seem to realize is that an elk is not just a big deer. A mature bull may weigh 800lbs or more. A bull moose 1500lbs. Seems a bit silly to me that folks would think their deer load is plenty for a critter that may weigh 7-8 times as much. Same for hogs, huge difference between a 100lb BBQ piggy and a 400lb bruiser with a 2" gristle plate. The super hard, heavyweight LBT's are without doubt, better bullets for those bigger critters. They penetrate MUCH deeper and create larger wound channels.

On hardness. If you're not recovering bullets because they pass completely through deer, then you really don't know if your bullets are hard enough. Deer don't take much killing, I've had 200gr cast hollowpoints at 800fps exit on a broadside shot. For example, the 265gr .45 Keith that I tested (far left) expanded considerably. As such, penetration suffered considerably. The undeformed .44 Keith I tested penetrated 50% deeper. Either would exit on a deer but which would be better for bigger stuff? The point? Any deformation whatsoever will have a measurable effect on penetration. The best penetrating .45 load I tested went almost twice as deep. Something you will absolutely need on something weighing several times that of a deer.

Meplat size. The meplat diameter is the only dimension that matters. It's not the bullet's overall diameter that determines the size of the wound channel. It's not the Keith bullet's shoulder. It's the meplat. To put things in perspective, a .45 Keith's meplat is usually .300". A .45 WFN is around .345-.355". I guess some folks look at that and think it's no big deal. Do you guys not realize that the 0.055" difference is greater than the difference between the .40S&W and the .45? Let that sink in. The functional difference between your favorite .45 bullet and a WFN is greater than the difference between the .40S&W and the .45Colt. Still think it's insignificant? It's not. The WFN creates a significantly larger wound channel and still penetrates deep.

Bottom line is that SWC's work fine on deer and normal sized hogs. LBT's just work better and the heavyweights are necessary on large game.
 
Full wadcutters don't fly well past 50yds or penetrate straight. The nose shape is extremely important, which precludes a noseless design like a wadcutter.
 
With regards to meplat size, there is a tipping point, both literally and figuratively speaking. In testing, full wadcutters tend not to track straight in flesh, nor in flight. The WFN is about as big as one can go to ensure deep and as importantly straight penetration with a resultant large wound channel.
 
If the heavyweight LBT's were not better suited to some applications, we would not have or need them. What people don't seem to realize is that an elk is not just a big deer. A mature bull may weigh 800lbs or more.

I assume that was directed at me since I posted the picture of the bullet.

I am not an expert on elk by any stretch, but I have killed four bulls and been present when two more were killed. Likewise I was the dude who gutted, skinned, quartered, loaded them on the horses and packed all six of them out of the wilds. So I know fairly well the difference in the size of an elk and a deer. The point of the picture of the bullet that penetrated 3 or so feet of deer was it should have no problem penetrating a bull elk broadside, which, in my opinion, is the only shot a handgunner should take on game of that size. Too, that was a relatively light load, yet it still penetrated quite well.

Seems a bit silly to me that folks would think their deer load is plenty for a critter that may weigh 7-8 times as much. Same for hogs, huge difference between a 100lb BBQ piggy and a 400lb bruiser with a 2" gristle plate. The super hard, heavyweight LBT's are without doubt, better bullets for those bigger critters. They penetrate MUCH deeper and create larger wound channels.

Who said they would use their deer load for elk??

Some of the claims regarding the WFN type bullets I believe have been mixed with a little pixie dust. Hear me out:

As mentioned in the previous post, it's a given that a bullet with a larger frontal area penetrates less, as in the case of the HP's and the deformed SWC. Yet somehow a .44 caliber WFN with a .345" meplat will penetrate deeper than a Keith style SWC with a smaller .300" meplat??

I believe we should each use the bullet in which we have the most faith, and in doing so there's no need in trying to convince everyone else they're less than intelligent because of their choice. I happen to follow the writings of Keith, Pearce and others who used and use SWC's, and base my choice on their experiences, and ultimately my own very limited experiences. For those of you who choose something else, more power to ya'.

Respectfully disagree.
So you don't think a larger meplat creates a larger wound channel? You don't think heavier bullets penetrate better? What do you base this on?

That wasn't directed at anyone.


The point of the picture of the bullet that penetrated 3 or so feet of deer was it should have no problem penetrating a bull elk broadside, which, in my opinion, is the only shot a handgunner should take on game of that size. Too, that was a relatively light load, yet it still penetrated quite well.
They do penetrate well but they also have limitations. Your picture actually supports my point. If a load doesn't exit on a deer, it certainly won't exit on anything bigger, given similar shot placement. Like I said, it will work fine on a perfect broadside shot and if you want to limit yourself to those, that's fine. However, the hunter using a heavier LBT won't have to limit himself. That SWC penetrated 3' of deer. The heavy LBT's are known to penetrate four to five feet of 3/4 ton bovines.


Who said they would use their deer load for elk??
The gist of the opposing argument is that these heavy bullets aren't needed. So one can reasonably assume that any game to be hunted with a handgun, may be hunted with a Keith SWC at 1100fps.


Some of the claims regarding the WFN type bullets I believe have been mixed with a little pixie dust.
All the claims are based on experience. What are the contradictory claims based on? If you guys think that a 300-360gr LBT has no advantage over a standard weight Keith bullet, surely you have evidence to support this?


As mentioned in the previous post, it's a given that a bullet with a larger frontal area penetrates less, as in the case of the HP's and the deformed SWC. Yet somehow a .44 caliber WFN with a .345" meplat will penetrate deeper than a Keith style SWC with a smaller .300" meplat??
Yes, a .45cal WFN with a .355" meplat will penetrate deeper than a SWC with a .300" meplat. Actually a lot deeper. Why? Because it's 100gr heavier and a superior design.


I believe we should each use the bullet in which we have the most faith, and in doing so there's no need in trying to convince everyone else they're less than intelligent because of their choice. I happen to follow the writings of Keith, Pearce and others who used and use SWC's, and base my choice on their experiences, and ultimately my own very limited experiences.
I believe we should choose the best tool for the job. Faith doesn't create wound channels, break bones or turn lungs to jello. Bullets do. Nowhere in this discussion has anyone's intelligence been questioned. What I do question, however, is the logic behind the argument. I've been reading folks like Elmer Keith, Skeeter Skelton, Ross Seyfried, John Taffin and Brian Pearce since childhood. Elmer Keith designed a great bullet that is still viable today but the latter three will tell you that heavyweight LBT's are better bullets for larger game. Where do you find anything to refute what we've said here in the writings of any of those guys?

Below is the chart that eldon referenced. You can see for yourself how a heavy LBT greatly out-penetrates a Keith bullet in either caliber. The media used is called Sim-Test. It has to be diluted with 30% water to equal ballistic gel. Undiluted, it is tougher than real flesh. We have no way to calculate how these numbers translate to real critters, it is best to use the data to compare one load to another. However, I would throw a wild guess that in real life, the loads would penetrate about double what they did in Sim-Test if no heavy bone is encountered.

So you don't think a larger meplat creates a larger wound channel? You don't think heavier bullets penetrate better? What do you base this on?

I disagree with this statement: "LBT's just work better and the heavyweights are necessary on large game." Yes, heavier bullets, assuming they are well constructed and stay together, penetrate more; it's called SD. However, when you have 2 bullets, one of which will penetrate 32" of a medium, and the other will penetrate 35" of that same medium, and complete penetration of the target medium is 24", it is simply irrelevant. There is no dead and really, really dead. Also, I think the average layman would be hard-pressed to differentiate between 2 .45 caliber holes in a carcass, one of which was from a bullet that had a meplat a few thousands larger than the other. Just MHO.

Heavier bullets carry more momentum. LBT bullets do work better. I am curious as to how you came to your conclusion, is it blind faith of do you have any empirical data you've gathered. Not being combative, but when folks make definitive statements favoring one design over another, I assume that they have drawn their conclusions based on actual testing. The larger wound channel from the bigger meplat is measurable and not pie in the sky or conjecture. So it's not just the penetrative capability I look at, it's the demonstratively bigger hole it produces. Most of this is moot if the largest animal you are hunting weighs in at 130-lbs dressed, however, when animals start weighing closer to a ton, you bet you backside that you want as much penetration and damage as you can get. I also don't want a bullet/load that I have to be picky about what shots I can take. I reject the notion that as responsible handgun hunters we should somehow only take broadside shots. Why? Perhaps if my chosen load is performance limited this is a good idea, but when you load correctly, you can take shots from a variety of angles and not fear that you don't have enough penetration to get to and destroy the vitals. And I do prefer two holes over one, but that's just me.

If one feels that a 250 grain SWC is in the same zip code as a 360 grain WFN, they are sorely mistaken. Use a 250 on an animal that can stomp you into a grease stain on the ground and things can get western really quickly. I don't take chances like that if I can avoid them, and by choosing the right bullet I believe you can stack the deck in your favor. But again, all of this is moot if whitetail is the only game on your menu.

If we were talking about strictly deer hunting and/or given the parameters you outlined, I would agree that they are unnecessary. However, we've stipulated from the beginning game that is much larger than deer. While the penetration one gets with the Keith bullet on deer may be perfectly adequate, it may prove to be insufficient on larger game. I'm sorry but it's folly to believe that a Keith bullet will have the same effect on a buffalo that it does on a deer. So would you choose the same 270gr SWC to hunt buffalo, moose or brown bear? Do you really think there is no proper application for 335-360gr bullets?

The difference is much more dramatic than that. As the chart shows, even the .44 Keith that held its shape was out-penetrated by 50% by a bullet 105gr heavier with a significantly larger meplat! Not a little bit, fifty percent!


Also, I think the average layman would be hard-pressed to differentiate between 2 .45 caliber holes in a carcass, one of which was from a bullet that had a meplat a few thousands larger than the other. Just MHO.
But it's not two .45 caliber holes. It's much more drastic. As I said, the difference is greater than that between the .40S&W and the .45. If you don't think a .45 makes a significantly larger wound channel, why aren't you using a .41Mag instead? You contradict yourself. Look at your own sig line. You either believe that size matters or you don't. You can't pick and choose when and where it matters. You can't say that the .45Colt is superior to the .357 because it's bigger on one hand and then arbitrarily dismiss the size difference between the SWC and the WFN on the other.

The difference here is that you think, we know. We know that heavier bullets work better on larger game and that the greater penetration they provide is necessary. We know that WFN's produce larger wound channels than SWC's. We've seen it first hand. Yes, you can see the difference. I didn't switch from using SWC's to LBT's on game for no good reason. I switched because they work better, significantly better. Believe me, I'd have been happy to stick with SWC's because they much more common and much less expensive. But you can't argue with results......or maybe you can, if your mind is made up and you won't be swayed by the facts.

I'm going to Texas in October to kill either a watusi or a water buffalo. Minimum weight will be somewhere around 1200-1400lbs. I'll be using the 355gr .44Mag load. I will NOT be using a 250gr SWC but anyone wanting to do so is welcome to try but I'll be backing you up with the .500.
 
if one could fit a 355 grain 44 caliber keith bullet in a revolver cylinder it would have already been done. the design is too long for the current crop of guns, revolver and long guns. sure you could load such a bullet in a "special" case and make it fit, but you would loose powder capacity and loose the benefit of such a design. until cylinders are lengthened, the lbt wins with its greater momentum (weight x velocity).

keith bullets cut holes with the full diameter front driving band, not the meplat. .429" is greater than .370".

each design has its place. good hunting to you craigc. let us know how it turns out and best of luck.

maxp,

this is my 45 cal. blackhawk. i have been shooting 325 grain lbt bullets @ 1275 fps out of it for the last 16 years. i haven't shot an elk with it yet, but it goes with me on every trip.

empty weight is 36 ozs., loaded weight is 42 ozs.. i'm sure the lighter weight is because of the aluminium grip frame.

you can zoom in on the pics and see the scale reading.

it kicks like a mule. with the stock grips my middle finger and trigger finger get bloody inside of six shots.

That's a myth. It's been proven time and again that the SWC's shoulder does not create the wound channel. Sure, it cuts clean holes in paper but the meplat is what produces wound channels in critters. By the time the shoulder passes through, the meplat has already pushed tissue out of the way. WFN's create larger wound channels and that is not an unfounded opinion, it's fact.
 
I don't consider Brian Pearce the last word on the subject and if you knew what I know, you wouldn't either. Ross Seyfried is head & shoulders above any other since Keith and prefers the LBT over all other designs. As do many other authorities on the subject. Including the author of the article in question. You ever wonder why no one bothers with super heavy semi-wadcutters?

Did Larry Kelly and JD Jones take to Africa in the 1980's with Keith bullets? Or did they use something heavier and of a different design? Come on guys, this ain't 1936.

You are right it is not 1936, this is 2016 where everyone is an expert, even in areas in which they have no experience. That is why I like to tell SEALs what to carry, cops how to nab a perp, and big game hunters what to shoot.
 
What's the deal with instability with the WFN and similar?

Do standard twist rates need to be tightened up a bit to catch up with bullet design?
