357 SIG reload data???

[abruzzi]

Am about to begin reloading 357 SIG on a friend's Dillon 650. We have primers, powder, used brass, 9mm bullets, and the correct die set from Dillon. Question 1: how much powder do we load in this sucker if we want to wake up with our head on the next day. Question 2: use large or small pistol primer? Plus, any other pointers you wish to volunteer -- in particular a source of data on the net. If you suspect this is my first venture in the reload area, give yourself ten extra points. Thanks.

If no one has a better answer for the the .357 Sig reload, I would call Sierra Tech Line 800 223 8799, Hornady 800 338 3220, or Speer 800 627 3640. When in doubt ask the the ones who do the testing.

The .357 Sig uses a small pistol primer. As far as loads go, you don't specify bullet weights, and if I were you, I wouldn't put too much trust in loads you get here (including me). FWIW, I use AA #7 for my .357 loads. You can go to their web site and get information about .357 loads with Accurate Arms powder. Hope that helps some.

The reloading pages of M.D. Smith have some infor on this caliber and if I'm not mistaken Alliant's website also hase some info on it. ( I think)

My first bit of advice is "Get thee to a gunnery" and buy a reloading manual quickly. Or visit the various web sites for the powder manufacturers, they will have the loads you need, but they seldom will give you the type of info you can get in the reloading tips and techniques section of a manual.

I second Mal's comments about getting a good reloading maual, maybe two. Should have included that tidbit in my first post! :)

bluedot works great and fill the case to stop bullet setback

Whatever you do, realize that you are reloading .357 SIG and not .57 Magnum. I know you know the difference, but people on here might not. I have been thinking about getting a .357 SIG barrel for my G27, but ran out of funds. I think that has taken a lower priority to an M1 Garand or two.

You do need to be careful, and check and double check when looking up load data. Can't remember exactly, but I think it's Accurate Arms who has load data at their web site that has 357 Magnum on one side, and .357 SIG on the other, on the same page that can be printed for reference. Yikes! Be careful out there...

And make sure the brass came from a gun with a fully supported chamber. Full power reloads shot from reshaped bulged brass tends to go kaboom.

.357 Sig Reloads
Agree with the previous wise members, get a good manual first.
I like Speer # 13 but there are plenty of others.
The .357 Sig is not a difficult round to reload, just be careful.
Have had good results with PowerPistol behind Speer Gold Dots (Speer # 4360) and Rainier 124 grain PFP.
The .357 Sig is a very hot cartridge. Work up to max loads. Watch the overall length carefully. Do not go below the published minimum lengths. Pressure increases very quickly in this cartridge.
Good Luck
Take Care
