Honestly, I worry MUCH more about bullet stabilization than muzzle velocity. I can lob a 300grn bullet from a .45-70 a LONG ways out there and still make a hit, only travelling 2200fps at the muzzle. As long as my muzzle velocity is consistent from shot to shot, I wouldn't necessarily care if it's a touch slower, or faster, due to a different twist.
Well i was also told that you can stablize a heavier or lighter bullet than your twist rate can shoot by using a heavier or lighter powder charge, but that seems too iffy to me. I've found that the listed velocity ratings in reloading manuals are wrong, but more of a ballpark number. I only believe what my chrony says.
