When I first started shooting 357 Sig I was shooting a buddies G32. I was carrying an FN FNX45T, and wasn’t interested in 357 at all. He said the Sig was getting through 3a easy with the Underwood ammo, so (even though I’m usually skeptical of boutique wonder bullets) I ordered some different loads out of curiosity. We bought different 3a panels and shot them with 357 Mag and 357 Sig loads. 357 Mag (forget which Lehigh bullet) only reliably penetrated 3a from my 4” 686. I have a 2” Kimber K6sLG, and it only penetrated 3a half the time. My buddies G32 with the 65gr XD sailed through every panel we could find easily though. I was skeptical about whether it would perform on meat like it does in gel, so we then bought pork ribs and pork shoulder. We shot the 65gr XD through a stack comprised of 3a panel—>pork rib—>pork shoulder—>pork rib. It penetrated all the way through easily. I ordered a G32.4 and a lot more 65gr XD that evening. I ditched everything else, and it’s all I’ve carried (off duty only, have to use G19M on duty) since. He has most of the pics, but here is the inside of the pork shoulder from that shot. It centered the bone, and pretty much grenaded the inside of the shoulder: exit from rear of shoulder with thumb for scale: took off a layer: Inside of shoulder could practically be turned inside out: I kind of wish we had videoed the G32 test on 3a and pork, but I guess it doesn’t matter. People would likely argue till the cows come home. I saw enough to convince me, and I don’t much care for all the caliber wars stuff anyway.lol That’s why I’m building a Sig-a-tized G35.4 with a 5.8” KKM barrel now. Lehigh got my account sorted out, so I ordered a batch of machined 65gr XD’s and some stamped (stamped/punched/drawn/die formed, whateva) 90gr “FTM-EXD” bullets to try loads with. I’m waiting on the stamped 65gr XD’s, but in the interim I wanted to see their first stamped bullets. I’ve noticed their new stamped bullets appear to be a different color, and while there are lots of various reasons why that may be, I’m wondering if they went to a softer copper for stamping. I also wonder if stamping may have work hardened the bullets.
