will you only loose 50 fps by cutting a 24" remington barrel down to 20"? is this with both factory ammo and hand loads? i honestly don't know is why i am asking.</div></div>
every barrel is different there is no true rule of thumb for cutting them down versus velocity loss.
We had a guy, cut a 26" 300WM down to 22" and only lost 30fps. you can figure about 10fps per inch, but it depends greatly from gun to gun. </div></div>
that's about what i was getting at. saying with certainty that he will loose "x" amount of velocity with a factory barrel may not be the best advise to give someone. the op needs to know what his intentions are with the rifle before he can make the decision if the <span style="font-style: italic">potential</span> velocity loss can be tolerated. i think it would be better to expect to loose more velocity than not and end up be disappointed because your rifle won't perform the way you need it to. if the rifle is used primarily for a 1k yard prone shooting, it would suck to cut it down expecting to only loose 50 fps and it ended up loosing 150+ fps. now if the rifle is used primarily for positional shooting inside of 500 yards and only an occasional 1k yard prone shot, the velocity loss, what ever amount that may be, may not make any difference to him at all.
