I have a hunting buddy who has recently gotten into reloading with my assistance. He has only been doing it about 5 months now and is happy with his results. However....... He called me last night and has just gotten a die for his 223 and had cleaned and prepped all his cases and was starting to prime them. He is using CCI small rifle and CCI small rifle BR primers. He is explaining to me that about every 4th case, he is having trouble getting the primer seated. I haven't loaded a tremendous amount of 223 but I have never had this problem. He is using an RCBS tool and is explaining to me that it appears that the primer pocket is too small to accept the primers? From my experience, using my RCBS tool, sometimes the tube that the primers fall out into is too big and the small rifle primers turn sideways, but he assures me that this isn't his problem. I need some suggestions, I went through everything I knew to tell him over the phone with no luck. THe only question is his brass. He doesn't know what kind it is. He bought 500 rds at a gun show. Some of it says L P, and the other says C - R. ????????????? Anybody have any ideas???? I am going out to see him this weekend and maybe I can see something that he is overlooking??
