Mine loves it But seriously, I can't make this thing jam if I want to. I've tried running 200 rounds of Wolf followed by 100 rounds of Brown Bear through it really fast to gunk up/heat up the bore and then ran a buttload of PMC and Centurion through to see if it would jam up...nada. Fucker kept firing. What a piece of shit. In all srsness though, are there any WMDers who have problems with steel cased ammo? Seems to be mostly idiots who hav problems with it...and there are a lot less of those here than Barfcom.
