Unique in Marlin 1894 .357

[FergusonTO35]

Hey guys. I have an early 80's 1894 .357 carbine with Micro Groove. I have been shooting the plain base Lee 358-158-FP with 50/50 lube over 6.3 grains of Unique and a small rifle primer. Accuracy has been quite good, better than I can hold. Is this a typical load for this gun and boolit? How much Unique is everyone else loading for this application?

I think that load may be upped a little, but it should be a fine plinker as it is.

Check Manuals!

I used 7,5 grs N 340 - burns clean.

Well the Alliant web site shows 5.2 gr of Unique as the max. for .38 +P and 6.0 as max for .357 mag (and you will get higher pressures in a .38 case due to less case volume). I would drop the load .5 gr.

I would not shoot those in a light framed .38 revolver.

For a .357 magnum case most agree that 7.5 grains of Unique is MAX.In my .357 Magnum I am shooting close to your data in both the Marlin and my pistols.

I use 5.5 Unique in both 38 and 357 mag brass with that bullet. I do mark them (the 38 spec.) as do not use in a handgun.

My Alliant manual lists 7.7 grains as max with a 158 gr. jacketed. If the seating depth is similar, all things else being equal, you will make less pressure with a cast slug. I shot tons of 158 cast over 7.5 grains of Unique. You load is well safe in my opinion.
