Are Federal primers larger than CCI?
I have been using CCI 250's in my 280AI with Nosler brass, but today I loaded some with Federal 210M's and noticed that they were much harder to seat than the CCI. On a few pieces of brass I was not able to seat the primer all the way, btw I use the Lee hand primer tool. Just curious if it is the Federal primers that are larger or if the pockets are smaller in diameter, I haven't had a chance to measure them yet, just wanted to see what everyone's experience on this was.

Both primers and primer pockets are made to the same SAAMI specifications. That includes a small range and with an interference fit even a quarter of a thousanth makes a difference. Any of them can vary that much in a single production run. Nevertheless, the cups are malleable so you should have no real problem seating them.

Doesn't Lee warn against using Federal primers in the hand primer?

Your not going to have problems with that priming tool and federal primers, if you do I don't wanna shake your hand. Also as stated all primers should be close but IME when the primer pocket gets loose I use CCI 250s that I've had a couple years because they measure .0015" larger then any other that I have, but be careful switching from CCIs to federals, you may have to back off a few tenths depending on how hot your current load is.

???? I've been using a couple of aged Lee primer hand tools for decades and have had no adverse experiences...

Not saying it won't work, but I think when I got mine a few years back it had a warning. I use mostly federal 215's and have loaded some but they put that out for a reason and so I stopped. Probably just an isolated incident but I like my hands too much.

There was no such warning with my tool which is about 3-4 yrs old. I do however only put about 10 primers in the tray at one time just to be safe.
