.30 Carbine Blackhawk v. .327 Fed Mag Blackhawk
Been bantering back and forth on another site about the merits of the .30 Carbine v. the .327 Fed Mag as pistol rounds. Looking at the data it seems apparent that the .30 Carbine is ballistically superior. Just visit the Hodgdon reloading data website.

With a case capacity of 21 v. 19 gr of H2O, the .30 Carbine simply has more space for more powder. And when you take into consideration the space available after seating comparable bullets, the disparity is even greater.

Hence, we see Buffalo Bore offering .30 Carbine rounds with 125 gr hard cast (BHN 21), gas checked, fat nose bullets --- primarily targeting the Blackhawk community.

One things that seems universally acknowledged is the .30 Carbine Blackhawk is accurate, VERY accurate.

Comments?

To be honest, I must admit, I'm not that experienced with the .327.

I had a .30 Carbine Blackhawk..muzzle blast and muzzle flash were horrendous..shooting a cartridge designed for a 18" carbine barrel out of a handgun's barrel is not a pleasant experience..IMHO
 
I don't see how the .30 is ballistically superior. I see the Buffalo Bore 110gr at under 1600fps and a 100gr Speer or XTP running around 1700fps out of the .327.

IMHO, the .327 is a better choice in every way. You get a rim, you get to roll crimp, you have a better selection of bullets. Not to mention the fact that the .327 is offered in the Single Seven platform instead of the bloated large frame Blackhawk.

There's a lot of misunderstanding about this. Powders aren't chosen for barrel lengths, so it's really irrelevant that the .30 started life as a rifle cartridge. Like the .22Mag, it is really "designed" as a handgun cartridge. Powders are chosen for case capacity and operating pressure. Due to its capacity and pressure range, the .30 Carbine uses the same powders as magnum revolver cartridges. It does not use rifle powders. Same for other small centerfire "rifle" cartridges like the .22Hornet, .218Bee, .25-20, .32-20 (heavy), etc.. The .30 is really loud out of a handgun because of its powder capacity relative to its small bore size and its operating pressure. Same thing happens when you load the .32-20 to its potential.
 
Id take the .327 mag for all the reasons Craigc stated plus the option of shooting virtually any kind of .32 ammo you can find (not to say that .30 carbine is hard to find.). Im talking about .32 acp, 32 s&w, .32 s&w long, .32 h&r magnum, .327 magnum and if you want to go the custom route get an extra cylinder so you can shoot that sweet .32-20 !
 
The quote below is from a retired gunsmith and Ruger Forum moderator concerning the .30 Carbine Blackhawk v. .327 Fed Mag Blackhawk:
Raw power .... the 30 Carb wins hand down .... and it is also very accurate. Versatility in different platforms .... the 327 Fed Mag wins .... don't know about accuracy. I sold my 30 Carb Blackhawk .... it was a tack driver and would drive VERY LARGE tacks at a considerable distances.

For a Blackhawk, I don't understand the point of either of them. Why chamber a large gun for a small caliber? It just seems pointlessly inefficient and to make matters worse, makes an already heavy gun even heavier. In a Blackhawk at a minimum I would want a .357 magnum which is much more versatile and commonly available than either. Even that is on the small side for a gun that size. I've seen you argue this point repeatedly, apparently on several forums, and maybe in a vacuum where these are the only two choices, perhaps the .30 is the more potent of the two, but outside the vacuum, both are somewhat silly chamberings for a Blackhawk-sized gun. I'd trade either for a .44 mag or .45 Colt Blackhawk in a heartbeat.
 
CraigC and Barry the Bear make strong cases. .30 carbine may have a ballistics advantage, but it's relatively small.

In favor of the .327 FM you have more gun platform options, more bullet options, and ammo versatility. And anyone who has shot the .327 out of a Single Seven or Blackhawk can tell you, it's a very accurate combination.
 
Again I have to tip my hat to Craigc, I see no superiority of the carbine round over the magnum out of a hand and as stated before you can get a smaller single seven frame making the bigger gun point a moot issue me thinks, but hey your money do what makes you happy.
 
Given a choice between the two I would go with the smaller platform offerings chambered for the .327 Federal Magnum, with the added bonus of being able to run just about any .32 caliber round with it. If I wanted something in .30 Carbine it would be an M1A1 Carbine.
 
I have both the .30 M-1 Carbine and the BH with 7.5" barrel, they are both very accurate, reckon I'm fortunate to have both. BTW I reload the .30 carbine cartridge and I truly enjoy both.

The data below is directly from the Hodgdon reloading data website.

.30 Carbine with 100 gr bullet
Maximum Load H110
Grains 15.5
Velocity (ft/s) 1,762
Pressure 36,100 CUP

.327 Fed Mag with 100 gr bullet
Maximum Load H110
Grains 13.2
Velocity (ft/s) 1,525
Pressure 38,500 PSI
 
If I'm buying a Blackhawk and I have a choice of cartridges I'm buying a 327.

It's a pretty neat little package and has about the same performance as a 30 Carbine.

The 327 will never replace the 357 pistol/carbine combo but it could be a fun little pair if Ruger would build a carbine. What are they waiting for, Christmas?

By the way, there are no more new 77/357 rifles anywhere. Gone but not forgotten.

I'm thinking about a 30 carbine BH. I have a 43 Inland and I reload for it. Just not sure I want the shock waves.

The enhancement in velocity only gives it a flatter trajectory and does not correlate to superior ballistics . Also the magnum round boasts a higher max pressure ceiling at 45000 psi while the carbines is around 40000. I'm not saying the carbine is a bad round just saying for the money you spend you'll get more out of the magnum round.

I agree with that.

I would go so far as to say the 327 mag will eventually make it in the market place. It might even move the 38 special along it's way to obsolescence. :what:
 
I think law aside, the 30 will be around in thirty years. The 327 may or may not. If it is, it will be in the same class as the 10mm, and 45gap. Despite marketing, the 327 doesent fit a real niche that will carry it long term. Just my opinion.
 
Would a lever or pump action rifle in 327 Federal be useful for much of anything? Or would it be too light for heavy work, and too heavy for light work? (My father used to say this explained why a next-door neighbor of ours was frequently unemployed.)
 
It is sort of a bizarre argument to engage in to begin with. Which caliber is the most powerful of the least powerful rounds for the Blackhawk? Or which caliber is second-weakest for the Blackhawk?

It would be a dream varmint rifle and short range small southern white tail carbine.

Doesn't matter how useful it might be although I do see some utility for the cartridge in a 2" revolver. Most of the things sold these days are sold based on marketing and peoples perceptions as a result of that marketing. All one has to do is look at the plethora of new cartridges coming on the market every several years. The 327 was a marketing ploy between federal and ruger to appeal to the got-to-have-new-stuff crowd that may prove to be successful. I hope it stays around. I didn't buy one when it first came out and probably never will because I own and load for a bunch of 38/357 revolvers and a rifle. If I were a new shooter evaluating 327 and 38 spl. in a 2" revolver for SD I would have to buy the 6 shot 327. The muzzle blast alone would stop most people.

It's worth noting that the 30 carbine velocity is from a 7" barrel vs a 5" for the 327 Mag. Two inches either way is going to change those numbers for both rounds. Not exactly apples to apples unless they both were fired from the same length barrel.
