Re: knocking a few inches off of barrel length
Sure it does, as do ergonomics, portability and handling.
For example, if I have to carry it for two days in a pack, and my maximum engagement range is 1000 yards, then if I can shoot a .496BC bullet at 2780 out if my 18.5" barrel and I am currently shooting a .496BC bullet ay 2980 out of my 26" barrel, why carry a 22lb rifle when a 14lb rifle will suffice?
