Could someone explain to me what the complaint regarding belted magnums is? I understand they are for headspacing. Aside from that I don't know of any other purpose or use for the belt. I hear a lot about how particular cartriges are better cause they have no belt. Could someone please shed some light on this for me? I have been around reloading and guns my whole life, but have just recently started trying to find more education. This site has a lot of insight that I have never heard of. I am not trying to start a ford vs chevy debate here, just trying to learn. I expect different oppinions, as it may be an opinion thing, so if we could stick with facts instead of debates I would apprece it.
