How short have you built or would you build a steel 6CM barrel before you get concerned about loss of long range accuracy? Let’s assume a medium or heavy sporter contour. Not worried about trimming weight but rather keeping a reasonable overall suppressed length. 9” can. Maybe a better question is to ask if 20”-22” would or could adversely affect performance? Not looking to get crazy short but would like to hear your input & experience. CF barrel builders please chime in also. Thanks.
