factory 108 and 105. I don't reloadHmm…maybe bump down to A5H0? How spicy was the ammo you were shooting?
I might try an A5h0 eventually for grins; however, this is just fine for the time being getting use to this gun/cartridge.
I also don't have the utmost faith in short, stubby mags anyways compared to their standard capacity counterparts and sheer spring length/tension dynamics.
If it starts failing to lock back on a Duramag 20 or higher capacity Geissele, that's more of a concern.
