[QUOTE="BobbyL, post: 405563, member: 14081"] I have a 30-338 LM IMP and its running the 180's at close to 3800 fps. I think with a little more barrel and some other improvements i might be able to get close. But thats a hard goal to hit. I have messed with some CT varients that will be able to do what your asking though... If a 338 Snipe tac will run a 225 grain accubond at 3800 the 180 would be well over 4k. Shrink the cheytac case a little bit and neck down you shouldn't have any problem being able to do it. But i believe you may be running into the end of that bullets jacket strength if your pushing them that fast. May have to try a solid projectile or a slowed twist to correct that. bobby [/QUOTE]
