that's what a box of warbirds is. $100 for 20. after you accumulate some brass you could reload for a lot less. but hell, they hold like 120 grains of powder! the lazzeroni's and the weatherby's that are based on the .378 case are sorta neat. i mean they shoot a fair sized bullet really fast and flat, but they are like packin' around a deer. in order to use all that powder they have to have a real long barrel, like 28 to 30", absolutely have to have a muzzlebrake on top of that, the action is a foot long, the stock has to be real heavy to take the recoil and in order to use the ballistics you best put a huge scope on it. you're lucky to be under 15 pounds and 4 1/2' in length. like i say, i've shot em all, and they are impressive, but i can't imagine haulin' all that around on my back or trying to tie one on a horse. i'm real confident out to 400 yds with my .270 and i'll shoot 500 or more if i have too. i don't see any reason to shoot any farther. i use my old worn out binoculars so i can't see stuff farther away than i feel like walking. all these new guns and optics are cool, but guys are trying to replace hunting skills with equipment. the experience of tracking down a buck or a bull is a lot more fun than shooting 800 yards at one.
