Just got of ICQ with a buddy. His G36 went kb on him. He was shooting reloads, most likely 200gr FMJ. He said he was shooting light loads one handed. Pealed the slide and bbl. I'll get some pics and a right up. He thinks something was wrong with the OAL of the round (too short) I dunno, and this may remain a mystery. Just watch your reloads! When I know stuff, I'll post it on here.
