Reloading 357 for Rifle vs. Pistol

This is the bullet the OP is using…..
Hornady sez to load them accordingly…..?!?

But, what does Hornady know about their own products…..!!!… 🤔

I may be misinterpreting some of the replies here, but basically the OP is over-thinking the whole situation. .357 Magnum ammo is .357 Magnum ammo, no matter what type of firearm it's fired out of. Therefore, within BROAD strokes, load data for .357 Magnum in a handgun can be safely transferred to use in a .357 Magnum rifle without fear of dire consequences. In fact, I'll even go further and say to never trust anybody who says "oh, you can load 'er upper/morer/betterer" just because you're loading a handgun round for use in a rifle. And yes, I have seen people write and talk about loading their .44 Magnum ammo hotter for Marlins "because rifles can take more powder." BUT IT DOESN'T WORK THAT WAY!

Faster powders get less benefit from longer barrels because the lower charge weights translate to lower gas volume, so you have less gas expansion to drive the bullet. Heavier charge weights of slower powders generate more gas volume, giving more gas to expand to drive your bullets, and thus more able to take advantage of longer barrels. But your usable range of powders is restricted to the case volume and operating pressure of the cartridge you're working with. Your .357 Magnum ammo doesn't care if you're firing it in a revolver, a Handi-Rifle or a Marlin 1894; maximum pressure limits are the same.

As for whether or not any particular powder/bullet/primer combination shows up in both the handgun and rifle sections of a reloading manual, it will depend as much on time/money/effort/what was contractually obligated than whether or not the "handgun" data is safe in a rifle chambered for the same cartridge.

While I no longer have them, I have reloaded .44 Magnum for 3 different rifles and 4 or 5 different revolvers over the years, as well as loaded 9mm Luger for use in both pistols and carbines. The only time I've ever gone looking for "rifle" data is to get an idea of what I should be seeing if I decide to chronograph any of my reloads.

Edited: @Soonerpesek , looking at the Hornady data again, the even better part is they have different max charge weights for H110 and W296, which are THE SAME POWDER! 😬
 
In rifle
W296/H110 for 125 and under
Lil'gun for 158 and above

In handgun
Medium pistol powder longshot +/-

The med will do okay for regular shooting in the rifle but if hunting you want all you can get and still get accuracy.

If you load too hot in the 92 the split bolt face will uneven the brass head. Go with slower powder to get more fps at decent pressure. You wont see it in a marlin but pressure would still be over spec.
It is funny because I chose Longshot specifically because it was in the middle. Not on the fast end and not on the slow end. Good speed but kind of in the middle. I do want to work up some faster loads (with slower powders) for hunting in the future.

I was simply pointing out what is in print from the bullet manufacturer that the OP is using…

There are also manuals that have different charge weights for HP38 and W231……

It’s still printed in a viable loading manual….
Not made up…. 🤔 :thumbdown:

ETA…. I’m not disagreeing with you however…

Be a trail Blazer and load n110. The few who actually load it will say yes, those that never have will say h110 is the most bestist

Believe me I am not trying to over think this but I am trying to make sure that I stay safe and that my new rifle works properly for many years. So my main question was is this safe. After reading everyones responses the answer seems to be yes it is safe. After looking at the Hodgdon website some more I think that the only reason they publish rifle data is to show the difference in velocity out of a longer barrel and only used a subset of the data for pistol loads. Thanks for all the replies.

If your need more speed go slower, pushing for speed with slower powders is much easier on your fine new rifle.
 
The lever gun teachers the monster mean crimp.... it also humbles those used to shooting all kinds of cool bullets in pistols. Keith 170 swc not going to happen 😭

Au contraire. I load and shoot that very bullet (Lyman 358429) in my '92 Rossi, and it functions perfectly. There are a few small mods one can perform on a Rossi to help them feed the longer bullets.

I just opt to keep them in my pistol. My marlin feeds 38 and 357 just as good. I'm not touching my elevator.
 
I use something like unique for revolvers assuming they're short barrel like 3 to 4 inch and h110 for rifle.
But if your revolver has like an 8 inch barrel then use h110.
 
Don't overthink it, or try to read too much into the data. The only issue would be if the load is so slow out of a revolver that it sticks in a rifle barrel but loads like that are typically not published in standard data.
 
I looked up the reloading data on Hodgdon’s website for .357 magnum rifle and Longshot is not in the list of powders.
The velocity needs to be high enough in the rifle, so the bullets exits the LONG barrel. 158 gr & heavier Jacketed bullets & fast burning powder may cause bullets to slow in the last 10 inches of barrel.

The powder is done burning early, the high friction of jacketed bullets slow the projectile. Stuck bullet.

More common in 38 special with 158 gr jacketed or heavier bullets. There is less Published data using heavy bullets for this reason. OR there is NO starting load given.
 
I have been reloading .357 magnum for pistol using 8.2 gr (8.4 gr is Hodgdon max load) of Longshot for 158 gr Hornady XTP bullets. This load has functioned flawlessly in the two revolvers that I have shot them out of. Recently I purchased a Winchester 92 rifle in .357 magnum. I looked up the reloading data on Hodgdon’s website for .357 magnum rifle and Longshot is not in the list of powders. My question is this just an omission or didn’t feel like including it thing and I am fine shooting these loads in my rifle or is there actually a reason that Hodgdon would not use Longshot as a powder for loading for rifle?

You might consider a subscription to www.loaddata.com as they have thousands of .357 loads, many you won't find elsewhere.

They actually have the very load and bullet you're using from Handloader Magazine issue #299. From a 20" Marlin, their velocity was 1452 fps.

What do you mean too hot. Over max? Why would anyone do that. Just get a 44 mag. H 110 is perfect for 158 gr
Too hot for the 92 bolt face. If you load to saami max pressure for the 92 it is too much and will uneven the case head with the 357 magnum has been my experiance. Lower part of the bolt is spring pressure and not rigid like the top. If you are not seeing a line shapped like the split bolt face you should be fine. Type of brass and powder may have some bearing on it also.

Too hot for the 92? No such thing, ESPECIALLY as a .357. The 1892 is the strongest pistol cartridge levergun action of all and even stronger than some rifle actions. The modern 92 is good to 50,000psi, in .45Colt. You may have some issue with your rifle but it is not typical.
 
If it squibs, you'll know it was too slow.
Use the same data. Just be careful with lighter loads. They can turn into stuck bullets in a rifle. I’ve had it happen.

I always stay with ammo that runs above 850fps in my revolvers, before I try to shoot it out of my model 92 lever. Even those are like shooting a .22 mag with the little carbine.

If I’m not mistaken (and I apologize if I am), the Winchester 92 has a rear locking mechanism which will allow your brass to flex and stretch a little at high pressures.

Some of my older reloading manuals actually warn about only using new or only once fired brass for max type loads in .357 lever action rifles because of this. Prevents you having to fish a split case out of the chamber. This is similar to too much headspace. Not just with the Winchester levers, but all .357 levers lock up at the rear.

That said, for the most part, I use the same ammo in my Rossi lever as I do in my all of my 686s. A 158 HJP over 7.5 gr of Unique is a great plinking load and very accurate. For hunting purposes using 158 JSPs or XTP-FPs, I do use new or once fired Starline brass charged with 15.5 gr of H110/W296.
 
I can't think of any 38/357 I have loaded that I wouldn't shoot out of all of my 357 rifles or pistols. I have some 9mm that are only intended for a few pistols or an SMG though (noted on the outside and inside of their container).
 
I just don't understand how this controversy got started. It's not like the different 45-70 loads. Slight difference between bullet manufacturers but never loaded a close to max load that didn't work fine in my revolvers and the 16,20 and 24 inch R 92's . AND I'm racking my brain to remember a flat primer caused by 35,000 psi. Full load of 296 or titegroup for 38's by the bucket full and never had a load problem. XTP 140 and 158 I use Hornady near max. Nosler use Nosler near max. Use near max because of powder measure plus or minus. Have a coffee can of .357 brass that's old enough to vote. Arm chair shooters. Parrots. Shout down, show off wise guys make this and the other .357 conversation going on ridiculous. No fun to be had here. Wish we could just talk about the different specifications. Wish some could just read the directions. Everything is written out.
 
A nice trigger job from someone who knows what their doing totally changes a carbine if your shooting for points. I wouldn't risk saftey or ruining parts, but their was a guy at NC Pala that was a dam lever gun magician. A peep and a globe site finishes them off nicely. A carbine can be a lot of things, from fun range toy to meet getter in the thick woods.
Not everyone is into points. But good point
 
I'd get a 41 or 454 before 44. Who wants to load two diffrent cast boolit sizes to Play with stupid 44 mismatched specs.
I have two rugers and one R92 44 man's I load for. The rifle will send an xtp 240 in the chest and out next to the bung hole on a large doe. Gutless meat retrieval on that one. But nothing I have is stupid. Stupid simple yes. I don't cast for 44 mag, I have a 44 special for that. So that's nice of you to tell what you'd get but that's what I have. When I feel .357 is too tiny for what I'm doing.
