[QUOTE="Dean2, post: 2315972, member: 26077"] Lord love a duck! Bolt face pressure DECREASES as the surface area of the cartridge head decreases, assuming the same nominal pressure, and vice versa. Pressure from a round being fired exerts pressure equally in all directions, having consideration to the surface area the pressure is being applied on. Thus the sidewalls of a cartridge actually get far more pressure exerted on them than the case head. In the case of a 338 Lapua, the bullet receives somewhat less pressure than the case head becasue the base of the bullet is smaller than the case head and far less than the sides. You disagree with me and have an opinion everyone is pushing it without even the most rudimentary knowledge of ballistics. I am done answering Gun 101 questions, try google and some reading please. Have a great day. [/QUOTE]
