Yes, you are wrong in thinking anything is going to work guaranteed. Factory will but that's it. It's not the manufacturers fault if reloads don't cycle. We have a whole thread here that will explain which loads work better than others and maybe an adjustable gas regulator too. Go to the top of this and search this thread, it will answer all. By the way, cartridges of the world states 50 grains of IMR 4895 is the military equivalent. That's what I use but I think I'll reduce it to 48 gr next time.
