I have a .338 LAI, as well as a 6.5mm and a .22-250AI....All customs, and I agree with with obtunded and mystic, people don't think they can shoot long range with small calibers, Mystic has witnessed my 250 out past 1000 yrds....
BUT (the other hand part)----> I personally dont worry about the $$ part, whether i am shooting $.50 rounds or $5 rounds or 10$ rounds, its my hobby, and I get a great deal of enjoyment out of it. (Yes I have gone shooting gophers with a .338LAI)...... With the limited time I have for my favorite pastime, I choose to place my fun above the $$ value.
A few years back, I shot well over 150 rounds of 338 with Jerry just for $hits n giggles over a few days of shooting (Still a fond memory out at summerland jerry!!!!)
Currently deciding on going the heavy pill 7mm route, 6mmbr or 6X47 Lapua route for the next one..... Oh decisions, decisions......
