[QUOTE="MagnumManiac, post: 2308688, member: 10755"] [USER=118038]@Veteran[/USER]. No, 41’s aren’t different in how they seat, they are less sensitive with a harder cup. All primers are designed to be seated below flush with the case head and have the anvil and cup crushed until they are flush with each other. This crush also pre-compresses the priming pellet slightly, which is a design feature. It needs this so that the pellet gets all of the firing pin energy. Different primer brands require different crush. Some only require .003” crush once the primer hits the bottom of the pocket, others .004” and military can be as much as .008”. Federal primers are sensitive to crush amount, Winchester not so much. Cheers. [/QUOTE]
