I'm relatively new to F-class shooting, I've been practicing for 2 years with a club rifle. I'm now considering having a rifle built, but I'm getting a bit confused. When asking my fellow club members I often get pre-formatted answers, but nobody can really explain the why. And the Internet is as inconsistent on that topic as on any other. So everybody around me is using 30-32 inches barrels, but I'd like to know what my leeway is.
My objective is to be able to shoot 308 Winchester club ammunition (155gr Sierra & ~45gr load) at up to 1200 yards.
If I understand correctly that bullet can go trans-sonic at that range without a high muzzle velocity, and the longer the barrel the higher the muzzle velocity. I understand that the longer the barrel, the more it can flex and bend, but that should be relatively consistent if the ammunition is. And also the longer the barrel, the heavier it is, so there is a weight limit.
Is there something else important I'm missing? Would it be reasonable (if not a little eccentric) to add 2, 5, 10 inches to the usual 30-32?
And maybe a more fundamental question: is there a way to estimate muzzle velocity based on ammunition and barrel characteristics?
