Feral 
I chrono'd my Ruger Mini 30 (7.62x39) at the range today alongside a CZ bolt action in the same calibre. Did it across several ammo types including handloads. The bolt action shoots pretty much advertised muzzle velocity as per the packet (say 2460 fps for PPU / Prvi. The Ruger semi however, 1600 fps give or take). Now 800-900 FPS difference to me seems like something is amiss. From looking online, advice seems to be that there would be a difference (gas cycling etc) but not significant.
800 fps difference seems an awful lot to me, so do I just need to accept this or is this an indication something is amiss? There was little difference between being suppressed vs unsuppressed on the semi. The barrel length is about 30mm shorter than factory due to removing the foresight and adding a thread.
Any insight would be welcome!
Cheers, Feral.
