357mag loads

I load SRPs with 6 grains Unique in .357 brass with a 358477 150 grain bullet. Shoots real nice, just over 1000fps in my 4" 686.
 
Well, made it to the range.

All of the ones I tried went off. Something odd I noticed, I had the lightest load of 2400(11.5gr), there was no powder residue issues, I shot 18 rounds and figured there would be some nastiness, but the gp100 wasn’t very dirty at all. Wonder if the hotter primer had something to do with that? No pressure or sticky case issues either.

The first cylinder full got zeroed in, and at 50 yards, it was constantly hitting soda bottles and cans. I’m happy with that, just being I’m out there for fun. Recoil wise, it’s snappy, but I could shoot all day with it, surprised me it had as much as it did.
 
357 magnum load - standard pressure - midrange load .
in 357 magnum case
157 / 158 grain cast lead or plated bullet

the following were developed for max. accuracy and are my "pet loads"

7.0 grs. Unique (1089)
4.8 grs. Bullseye (910 fps)
16.5 grs. H110 (1240 fps) (magnum pistol primer)

Use what primers you have/can get and see how they perform.
During these times you have to use whatever components you can get .

7gr unique 210gr gdhp is what works for me in 44 special. That’s a golf ball at 50 yard load.

Once I finish the can of unique, I’ll try the bullseye powder, I’ve never tried it but hear nothing but praise.

I have a partial can of H110, after beating myself up trying it in the srh, it’s been banished to desert eagle duty. I fired 3 rounds, pulled the other 9, no fun at all.

I was trying 2400 first for 357 as I have more of it than unique or bullseye, it worked great, wasn’t hard recoiling, and surprisingly wasn’t nasty. The special and magnum 44 loads I have for 2400 are dirty as ****, but are accurate.
