I really love 7625 in 9mm and .38 Super, but when I loaded it in .357 with 125 LFP's I got wild velocity swings.

I've used 4756 in .357 with 158 plated FP's with very good results. I used it as a substitute for HS-6 and won't be going back. Much cleaner burning (virtually no unburned powder, an important factor for revolver shooters IMO. Plus you don't need magnum primers with 4756.

I'm hoping to try 4756 in 9mm here soon, the ballistic charts look very impressive as far as high velocity and low pressure.

No experience with them in .45acp, but I would think 7625 would be an excellent performer there.

Both meter perfectly for me.
