[QUOTE="swampratt, post: 3138334, member: 15054"] chambers are cut different but you can have a tight 5.56 that is tighter than a loose .223. In my load work ups in many different guns i find some barrels are faster than others ..You guys I am sure have seen that also. Tighter bore vs a looser one should increase pressures. I can pull a bore snake through my .308 savage with minimal pull strength. Take the same Bore snake and I must wrap the string around my hand to pull it through my Mossberg 30-06 ATR. One 18" barrel .308 savage I have shoots the same velocity as a Ruger 22" .308 I have. I have heard one guy tell about 3 different 30-06 ATR rifles.. 2 had mild recoils and one was a shoulder punisher. Mine is a shoulder punisher. It is also a very fast rifle. I think there is much more to the pressure situation than just the chamber cut..You must look at other aspects. [/QUOTE]
