[QUOTE="kraky2, post: 235173, member: 3532"] I doubt anyone knows for sure but.....the two bullets you want to load are going to make more pressure than normal 180's. So....if you want to use the powder I'd weigh about 5 of the loads and average them. Then with the 180 e tip I'd use the same powder at about 4% less charge and the 200 ab's at about 6% less charge. Then I'd work up slightly by using a chrono. The factory wby 30-378 that I checked years ago over the chrono were doing only about 3300 with 180's..you should be able to get near that with the e tips. I think about 3150-3200 will be the desired ceiling with the ab's. BTW---you will probably have to resize the neck area to have good neck tension to hold the new bullets. [/QUOTE]
