Can any of you tell me what the best barrel length is to get the best velocity out of a T/C Contender Carbine in 7-30 Waters? I'd like to maximize velocity without having an overly long barrel if possible. I have a 24" barrel and am considering having it cut down a little bit but don't want to sacrifice too much velocity. The 24" just seems a little bit long and ungainly looking to me. I was thinking maybe 22". What do you think?
