What kinds of ammo are you guys putting through your SA-M5's? I had mine out once so far and put about 200 rounds of Wolf .223 62gr. FMJ through it no problems. I'm waiting on a PK-ASV optic to sight in on my SA-M5S to see how much more accurate it is than my SAR 1. Also wanted to know what's a good defensive/SHTF type ammo to use?
