357mag load data

[dbbspider]

I use W 296 powder and cci
magnum primers in my 357 and 500 S&W reloads with no problems. I use fmj in the 500 though

Winchester does not make Magnum Primers. Only primers that work with either standard or magnum loads.

Check your data again....that's only large pistol....they make 2 for small pistol both mag and standard...WONDER WHY?

Actually...We have Winchester large pistol mangum primers for the 44mag and cci small pistol magnum primers for the 357. my mistake.

If your sure that those plated bullets can handle the velocities your getting go for it. If you want some real magnum loads 1600+ fps try H110

I wanted 2400 when I started 357, they only had h110. I put 13 grains under a 158 bear creek Molly swc and mag primer, light magnum load, still a bit heavy out of my 2.75" barrel. I've gone to 5.6gn of bullseye as a nice target load which would be good if shtf too. Give h110 a try. It needs a mag primer and heavy roll crimp. It rocks the lanes hard and makes my box of fired brass jump.

2400 is absolutely a magnum powder and will get you all the velocity you would need. Sometimes you'll get a little more velocity with other powders, but the difference isn't that great.

Allied, I know you said the bullets have a cannelure, but if it's like most xtreme bullets, it might as well be non-existent. It sounds like you're on the right track using a light crimp and staying away from max charges. Good luck.

Maybe he'd get 1600fps with 125gr bullets, but there's no way he's even getting close to that with the 158gr bullets he has unless it is out of a rifle.
