.357 SIG powder and bullets recommendations

[Guns4545]

MA has a swage combo with their decapper so you can swage 5.56/7.62 NATO and other military type crimped brass. I got it with mine. Really useful and effective.

Nice. I'll check it out.[emoji106][emoji106]

Is this the correct MA for small lapua size flash holes? I want to get one for my Lee singe stage. https://www.mightyarmory.com/collect...12346027802702

I am just getting ready myself to reload 357 Sig, still gather all the needed items. I click on this link and it doesn't find it. So which MA die is it that you found worked? Thanks for the help, Bob

Thank you much.

Do you think power pistol would be a good choice for xtreme 124gr fp? What coal are you running?

Also for 125gr Speer gold dots would Longshot be the best choice?

Just use Western Powders suggested charge for their 124/125 grain for AA#9 (11.7 - 13.0 grains and COL of 1.140"). The Xtremes can handle the velocity, I've run them at 1,450fps and they shoot fast, flat, and accurate. However for plinking I've backed off a tad to save on case life. I run em around 1,320fps now. Very accurate.

Edit: be careful on certain brand cases of running near max or max loads.. the AA#9 powder fills the case FULL and the compression from seating the bullets can bulge the shoulders and cause the rounds not to feed or chamber. Different cases have slightly different internal volumes. I've found this out using mixed headstamps.

Thanks bud. Any cases that come to mind I should be aware of? I'll never go max anyways. These will be plinking rounds.

I can't remember which one's had less volume, but I run around 12.5 grains for plinking and it has kept shoulder bulge away.. All my hollow points.are loaded with same headstamp so I can run hotter.

What headstamp do you use for hollow points?
