Any experiences with it? Their 357 SIG is damn cheap.

I've shot a couple thousand rounds of .223 with no issues.

I've shot plenty of the .223 and .45, it all goes bang, but it's a bit dirtier than some.
Some of the .45 had trouble chambering in a brand new MP45 due to not-quite-right resized brass, but I polished the ramp/chamber transition where it was sharp and everything was good after that.

I bought a can of .40 and have shot through about half already with no issues. Everything went bang, accuracy is reasonable, price is great and the free .30 cal ammo can is a nice perk. It was back-ordered when I placed my order but it shipped well before the estimated delay. Nothing but good things to say about it.

I've been through 1,000 rds of 40s&w. No issues.

Used it for years, gtg

Have shot ~700 rounds of 223. No issues.

I have fired 500 rounds of their .357sig.125g.FMJ through my G31C with no problems at all. My 500 rounds was all assembled using Speer nickel-plated cases (I suspect this came from a LE training range) and every round looked good. I was very happy and will be ordering more.

However, there is another thread where a member found a cartridge in his order that the primer had fallen out of (while in the box/can) and he was concerned about the quality of the rest of the rounds. I don't know how that turned out for him.

FWIW- I have fired several thousand rounds of their .38spl., .357mag. and some of their .45Colt and 10mm. I have never had a problem with any of it. Georgia Arms is an ATF licensed manufacturer and they use commercial equipment and follow industry standard safeguards. They are not Bubbas in a garage with a progressive press.

I've used up almost all of my 1000 9mm and 1000 .40 and had no issues.  Will buy again if price is right
