Not really Mathman, everyone knows that to shoot a boat tail bullet in a 300 W or S the bullet still must be seated lower in the case. It has nothing to do with a certain caliber or cartridge. It has everything to do with getting a bullet seated straight w/a good grip and it's hard to do w/a short neck cartridge. Now there's always the guy that comes along and says mine shoots boat tails fine w/an .055 grip on the bullet. The problem w/that is I've just never met him. And don't give me the age old, well the target shooters often have very little grip on their bullets. That's an entirely different discussion. You might want to go measure yours Mathman, just as a point of interest. You see there's not one in ten that can tell how far down in the case their bullet sticks. They all can tell what their COL is but don't have a clue what grip they have on their bullet. powdr
