Well it's happened to me again. I just spent a frustrating hour loading 100 .45 acps on the old projector. Almost all of the primers were seating proud of the case head uness I really crunched them home. When I finished that tube I took a close look at what was going on and I've got a case of 5,000 CCI LP primers that have cups measuring .1115 deep. I checked a different lot and the cups are .1090. Anyone know what the Saami spec for LP cups is? I checked a few of my remaining WLPs and they are .108, and they seat just fine. I am not looking forward to reaming 5,000 primer pockets so I can use these.
This is the third screwy lot of CCI LP primers I've had. About five years ago I had a lot which had all of the anvils set up so high that they wouldn't feed through the progressive press. I loaded them all on the rock chucker. Back in the 90's I had a lot in which many of the cups were taller on one side than the other, they'd seat but it sure felt odd seating them and they all had one edge crunched a bit. About one in 50 would wind up sideways coming off the primer arm which was a major PITA.
I guess it's back to mail order. CCIs are all I can find locally.
