You say similar weight; the closest "similar" I see for that cartridge is 10grs lighter. Do you think I can start at the upper lmit for the lighter bullet? Thanks again.
With the small % weight difference between 275 gr and 285 gr I'd say that bullet construction/bearing surface differences will probably be more of an issue between the pills than the extra 10gr load as far as pressure is concerned. I'd simply start 10% down from the top for the 275 and expect to fall a couple of % down at top charge.
