I am going to have a rifle built on my old Mauser action. I believe I am going to go with the 30-06. Rifle is primarily for hunting. My question is about the length of the barrel. I typically use 24" barrels but I am wondering how much velocity gain would be with a 26" barrel or if it is even worth it? Gun will be fitted with a laminate stock so I am thinking the weight of the stock would help with balance.
