I have collected a lot or .45 brass over the years but never reloaded it till a year or so ago. I have some 230gr Ball that I pulled from some cartridges that the primers were all bad. I also have some LRN that I sat a while ago so I decided to load up some .45. While priming I found out that while most .45 is large pistol, there is some out there that looks like small pistol. What are the differences aside from the size? After the last drought of components I as thinking it may come in handy to have .45 brass for both primer types. Aside from that I can't think of a reason to have both. I would love to hear some input from the reloaders here. Thanks!
