I got it. I opened the rear tabs just a touch and all is well. Son I did get some of your rim locking because of my thumb position as well but that wasn't the whole problem as the bolt would ride over the second round without picking it up. The rounds were further back in the magazine so I guess the rear tabs were not allowing the following rounds to move up high enough. Strange how just taking the time to look makes a world of difference. Of coarse you guys telling me where to look helped immensely as well.
Thanks for all the patient answers to newbie type questions.
