My LNL AP press does not like CCI small rifle primers. It will not feed them about 3 out of 10 times but it feeds Winchester and Mag Tech small rifle primers perfectly. It also feeds Winchester small pistol primers perfectly also. If I fiddle with it I might get it to where I have trouble with Winchester primers, oh woe is me, what to do, what to do. LOL.

That is about all I use, but I have the Pro Jector; which uses a swing type priming arm; they changed it on the LNL. Not sure why.

Years ago CCI small rifle primers ran on the large side. They were a real bear to get flush and took a considerable amount of effort to seat. I stated using Fed primers and the problem went away.
