So after falling in love with my .338 edge I have decided I want another .338 cal cartridge. I am looking at a stiller tac .408 action and building a . 338 snipe tac with it . I have got a 31 inch barrel on my edge and a brake as well and it makes for a loooong rifle . I would like to keep this one shorter. My question is what is the shortest barrel I can get away with and still keep this worth while ? If I loose too much I might as well go with a .338 lapua imp. . I'm hoping 27 or 28" will be ok.
