I am going to replace the nipples on all my percussion arms. There is a Traditions, a CVA, a T/C and two Pedersoli's. First, I would like to stick to one brand that can cover all (with appropriate threads) if possible. Second, I would like to learn why one brand may be better than another. I admit I asked this question elsewhere but I got a really limited response (really only one). There is a large audience here with a lot of knowledge so I look forward to your responses. All are rifles but one Pedersoli that is a smoothbore. Thanks in advance
