So, I'm new to reloading. I bought some Norma 5.56 55g FMJ at a good price, but I found that they were not as tight groups as the other brands I have purchased and I would frequently get jams (I can't remember how exactly) with these round, so they went on the back shelf. I have reloaded most of my other brands and I decided to try reloading the Norma. This is my process with all so far: Hand de-prime, clean, then size. But with sizing these rounds, they take much more effort with the press than the other cases (PMC 5.56, Hornady 5.56, Frontier 223, AAC 5.56) Anyone else have this issue? I've stopped after sizing 20, and I wonder if I should even bother, especially if they are going to continue to jam. I'm going to take some measurements of the sized Norma and compare to the other sized cases, maybe the sizing process corrects the case, and I shouldn't have any problems.
