You are right Larry. A couple of 10thousandths make a big difference. They also make a difference in pressures. I had one 22-250 that shot faster than the other.. Both Rugers. Accuracy was about the same but with the same load..one would almost lock the bolt. Very stiff lift. The other was fine. Same load and almost a grain under max book loads..Velocities were not even close... more than a 100 fps difference higher with the maxed out rifle.. but with all that said..the shorter bbls usually shoot slower. sometimes quite a bit in the smaller bores. My 243 is a 22 inch one. and will not reach the manual speeds..close but no C gar
