I just got into reloading about a month ago. .45ACP and .308 are working just fine out of my 1911 and Remington 700 but what I'm putting together for my AR isn't working out so well. The bolt isn't going the whole way forward with my reloads. They also don't come out all that easily when I pull on the charging handle. Takes a few smacks on the buttstock to get them to come out. I made sure that the case goes as far into the sizing/decapping die as it'll go. The bullet is seated to the same depth as factory loads. OAL is also the same as Hornady V-Max rounds. I do NOT have a case trimmer, I'm guessing this might be my issue but I wanted to ask since these are once fired cases. Any help would be greatly appreciated.
