[QUOTE="reed mosser, post: 75350, member: 1589"] i have pretty much the same thing with a 30-338 laupa mag with a 35 degree shouder. In my 30 inch tube I shoot 98 to 100 grains of IMR 7828 to shoot the 150 hornadys at between 3700 and 3800 FPS. I don't know what grain bullets you are going to shoot but it should be similar to the 30. With 120 GR bullets the 9 twist I bet it will shoot at around 4000 FPS, good under 700 yard hog load. Good luck , its good to see someone pushing ballistics to the maxium. Reed [/QUOTE]
