Sig 357 reloading

[rpenner]

Has anyone tryed to reload 357 Sig. I'm thinking of buying one but I need to reload as factory ammo is pricey. Can you use a 9mm 115 or 124 gr bullet. Any idea's or comments would be appreciated...

From what I've read 115 and 124 gr bullets is what you use.

For what it's worth, if you haven't bought the gun yet you might as well go with a 9mm or .40, but thats just my .02

I might get the 357 sig barrel for my Glock. Not sure why but the bottle shaped round interests me as well.

I've reloaded a substantial number of 357 sigs. If your still interested let me know.

I was interested as well untill I heard that you can't form 357sig brass from 40 because it will be to short. This might be heresay so some input from those on this site could clear this up. Not quite a 357 mag but awfully cool!!

Double Tap sells starline 357 Sig brass

you can form 357 brass from 40 , but you have to head space on the shoulder rather than the mouth , & you end up with a bit shorter neck .

There are a few IPSC shooters who neck down .40 to .357sig and do it in large quantities so it is not unusual or difficult. As mentioned above the neck is short so headspace on shoulder.

I have not loaded for the 357 SIG but have researched it a bit. I read that typical 9mm round nose projectile profile don't work well with the 367 Sig as the ogive doesn't line up properly with the case neck. This puts the rounds at risk for setback which can be dangerous.
Most people loading favour the truncated cone shape bullets that are less common for the 9 mm.

Now if you are loading for a 1911 and can load long the round nose may be loaded long to get around the problem as long as the gun will feed the longer loads.

With the cost difference between 40 and 9 bullets growing I was looking at the 357 sig as a way to save some $. In order to make it work for me I would have to neck down 40 brass otherwise the savings for bullets was out weighed by the cost of brass.

.357 SIG was the only way to make major in Australia (still is) as the calibre limit for IPSC is 9mm, .38, .357

I used to reload all the time using a 165 gr pill, in a Dillon 650

The only real issue was to use case lube.

I always used Starline brass, but there were plenty of people necking down .40 cal brass

9x40 open; It's a noise maker

I have fairly extensive experience reloading for 357SIG, and I love the caliber.

You "can" resize .40 brass to work...should you? Thats all about what you feel comfortable with. I do it and I've never had a problem.

I've used a number of different bullet weights and profiles ranging from <100gr to 147gr... once again, it "can" be done without too much effort...if you're willing to take the risk.

Personally, I'd say that if you get your dies set up properly and use a 124gr bullet that has a short ogive so the case neck has something to grab onto, then you won't have any problems. If you're really worried, find a powder that takes up lots of case space and it will prevent the bullet from moving if your neck tension isn't quite up to par.

Bottom line: Do it!

I bought a Sig. about a year ago. I really like the round. I've had my best luck with 125 grn Truncuated Cone bullets and Blue Dot powder. I bought range brass over on ar15.com.
