Does the face of the hammer strike your Nipple square? If not , remove the high spots with a dremel tool grinding bit, and that should cure the misfires. If you look carefully at the top of your nipple, after 25 strikes or more, you should see the beginning of " Peening " of one edge of the nipple. That inturns makes the side of the nipple just below the top bulge out, making it more difficult to fit the cap on the nipple. But worse, that bevel made by the peening of the edge or the rim means that while the rest of the cap is square to the nipple, there is nothing under that section of the cap to act as an anvil when the hammer falls. That makes the hammer flatten that side of the cap down on the beveled edge, and then the second strike fires the cap.
UseMarking die, lipstick, a grease pencil, or something to mark the top edge of the nipple. Then lower the hammer down on the nipple to mark the high spots on the face. Grind away the high spots, until you can take a piece of paper towel, fold it over, place it on top of the nipple and pull the trigger so the hammer falls from full cock to hit the nipple. With a new nipple under that toweling, the hammer should make either a clean " Punch hole" , or at least make a complete circle mark on the toweling. Don't stop removing the high side just because the circle is complete, if the circle is still " thin " on one point in the arc. Whatever line is left by your nipple on the towel should be evenly thick around the circle.
When you marry the face of the hammer to a new nipple, you nipples will last much longer and not be shortened so fast by the repeated hammering of the nipple by your hammer. If you shoot every month, and practice, you should be able to get buy with changing nipples once a year, or less. Other factors, such as the brand of nipple you buy, or make, the diameter of the hole through the nipple, and what kind of load you shoot will also affect nipple life. If you are shooting the subs, rather than BP, you should expect shorter nipple life, simply because those powder burn at much hotter temperatures, and heat will wear out the tiny hole in the nipple, eventually.
I've always had CCI caps & primers go bang when the hammer fell, can't say the same for Remington. :cursing: Given the number of times they have failed to bang when they were suppose to, I will not trust Remington for anything serious. Playing around maybe.
