[QUOTE="Pdvdh, post: 1083784, member: 4191"] You might want to place a few of your A-Max bullets between the two jaws of your calipers in order to confirm that the base of the bullets at the junction where the boat tail merges with the bearing surface body isn't a larger diameter than the rest of the bearing surface. I had a box of Nosler Accubond bullets years ago which had a larger diameter at the junction of the boat tail and the bearing surface than the diameter of their bearing surface forward of that junction. I called Nosler and they replaced that box of bullets and said something about their bullet forming die may have been out of spec, or worn out of spec over time. Those Nosler Accubonds would spin around freely between the jaws of my calipers, only making contact with the jaws at the boat tail/bearing surface junction. This condition will, of course, expand the brass case necks more than necessary as the base of the bullet is pressed/seated into your case necks. [/QUOTE]
