I have a Savage 6.5 CM that I'm going to rebarrel with a 22 CM. I have enough 75 grain A max bullets to wear out the barrel just can't decide on a barrel length. 22, 20, or 18 inch length. I was wondering what kind of velocity drop I can expect between barrel lengths I was guessing about 40 fps per inch. Does that seem right?
Was thinking that reasonable velocities would be about
3330 in a 22"
3250 in a 20"
3160 in an 18"
Any one have real world numbers for velocities?
Thanks
