I've got a Tikka T3 lite that I was thinking about cutting down to 18-20" from factory 22 3/4". Besides loss of 200-300fps will it change the accuracy?. This gun shoots rally good as it is and don't want to lose that accuracy. By the way this is going to be primarily a mountain and deer gun. The reason I want to do this is after carrying the Ruger MkII frontier 16 1/2" in .308 and not getting hung up on devils club and alders I got kind of spoiled.
