.357 SIG powder and bullets recommendations

[Guns4545]

I bought all the brass he had left a lil while back LOL. There seems to be a drought with the SIG brass at times like now. If you go with Starline, at least you will have all same head stamp. Starline is good stuff in my experience. Keep in mind, if you get some mixed brass, there are regular sized flash holes and small Lapua sized flash holes. I always decap with my Mighty Armory decapping die and Lapua decapping pin before I stainless wet tumble them. I remove the decapping pin from my 40 & 357 sizing dies so that there is no issue with sizing them since they are already decapped.

I use the Lee universal decapping die for everything then wet tumble. Will the Starline brass have the correct size flash hole for the universal Lee decapping die?

Not sure what size the starline is, don't have any in 357 SIG. I've used it in a few rifle calibers though. If the holes are the small Lapua size, you can probably punch through them, but the easiest thing would be take the pin out, put it in a drill and whittle it down with some sand paper til if fits in the tiny holes just barely. I did that to my LEE as well and if you break a pin after you've done that, then something is wrong somewhere besides the pin. I've decapped thousands of rounds of crimped primers with it and no issue at all. Just changed over to the MA die since I use it on a separate set up now. Still use the LEE on my turret set up for brass prep.

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

That is the correct one. Very good unit, tough as it gets.

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
