reloading 357 for rifle?

Can anybody share their favorite loads for 158 RNFP that I could shoot from my Marlin lever gun? Looking for 30 to 50 yard accuracy. Thanks....Marty

Herco Herco and more Herco.
It will give you more velocity for the same pressure as Unique.
Try between 6 and 7 gr see what that gets ya.
Also try 5 to 6 gr Unique.
Herco is a slower burning powder seems to work real well in pistol caliber rifles.

I couldn't find a photo of my 158 gr load but here is what I get from 38 special cases and 125 gr rnfp's and Herco at 50 yards.

158 JHP with W296/H110 shoots great in 1894C

Consult your favorite manual for appropriate data.

If it works in the revolver, it will work better in the rifle. All the load data uses the same powders although in some cases they back off the max loads by a fraction of a grain for the rifle because the lack of a cylinder gap leads to higher pressures.

For 30 yards to 50 yards accuracy with a 158gr lead bullet all you need to do is shoot your normal 158gr .357 Magnum handgun load in your carbine. With that short a distance no special attention is needed to attain high accuracy with a Carbine. The much longer sight picture will help a lot there, it does with my 1894C.

If you decide to try heavier bullets for hunting let me know and I'll post some data I worked up and tested...

H110 at any weight listed in the manuals. The min/max only varies by around 1.5 grains. I shoot near the upper end because that's where the autodisk happens to drop the charge at. Why shoot a magnum with any other load besides a magnum one? That takes all the fun out of it.

What velocity should I be at for lead cast? Most of the 357 formulas push it pretty fast. Marty

As fast as you can go without leading. With proper lube and alloy selection pressure will be your roadblock.

I used to love the Lyman Cowboy 158 gr. bullet with 2400 powder. Was very accurate to 125 yards, which was the farthest it would shoot before beginning to fall.
