I want a Rem 700 SPS Varmint chambered in 204ruger. It comes standard with a 26" barrel with a 1 in 12 twist. Do you guys think it would be dumb to cut the barrel down to 22 or 20 inches? I just want a shorter, lighter, easier to handle rifle. How much velocity do you think I will loose. I plan on shooting 40 grain bullets handloaded.
