[QUOTE="backwoods83, post: 598914, member: 29890"] I can tell you how to duplicate the factory weatherby 115nbt loads, its 67.5 grns MRP 3.210" oal and since they have their own primer you will have to subsitute Fed215Ms and use a .002" roll crimp, note this load runs well over book max pressure(about k psi) but weatherby sells them like that and they shoot well, another note, this was as of 3 years ago, may have changed but with a 26" barrel they will go through the chrony at over 3400fps.
