[QUOTE="dgr416, post: 2287548, member: 1208"] The faster you shoot bullets and more powder you shoot the quicker you burn out your barrel .I never knew why people didn't like a 243 in a AR 15 it's because the barrel only last about 1000 rounds when you shoot 55 grain bullets at 4000 fps you barrel will only last about 600 rounds or even less .The 30-378 with light bullets is known to burn out a barrel in 250 rounds with 150 grain bullets .My 338-378 would do the same thing with 160 grain bullets at 4000 fps .I would stick with 180 grain an up in that 300 win mag for big game hunting .They have way better energy at long range than the lighter bullets and your barrel will last way longer .I bet a 300 win mag with 4000 fps loads would not last more than 600 rounds if that .My 300 win mag which I only shoot 180 to 200 grain bullets in has shot at least 1200 rounds through it and is still shooting half inch groups .If you like buying barrels that 4000 fps load is for you .I didn't like the bullet blow up in the 300 win mag with even 150 grain bullets or even 165 grain .It blew half the deer away too with those lighter bullets .
