LocoGringo Posted March 26, 2012 Report Share Posted March 26, 2012 I've got an 18.5" Criterion barrel on my DPMS and am wondering what kind of velocity I might expect out of 175 grain ammo versus a 24" barrel. Twist rates are the same and both are .308 versus 7.62x51. Quote Link to comment Share on other sites More sharing options...
