trouble seating primers in LC brass

[Rdlningcltchdmpr]

How can that occur ? The swager goes into the primer cup and removes the crimp, does not enter the inside of the cartridge case, from the mouth of the case and inside, where the flash hold burrs are.

I learned the hard way that when anyone asks a question you should expect 50% good advice and 50% bad advice.

I need some guidance on seating primers in LC brass. I took pains to cut away the crimp. Using a Lee priming tool and CCI primers. When seating require high force and then snap in suddenly. resulting in misfires. I think the pellet inside is often cracking up. Will a primer pocket uniformer help? When I use Lapua brass everything is smooth and results in good( no misfires) results. Is this typical of LC brass

I finally gave up on once fired range brass , lake city and others with crimp primers. One issue to pay close attention is when you use extreme force to seat a primer you often bend the extraction rim on the case. It's hard to see but if you set the case on a flat plate the case will wobble because of the bend.

It certainly does enter the case.

Interesting. But all my swager enters and swages is the primer hole and base of the cartridge to remove the crimp from crimped cases. Oh Well, I guess I have been fortunate, have removed thousands of crimps and never had a issue, like some seem to have.

There is a pushrod that enters the case mouth and supports the case against the opposite swaging action going on in the primer pocket.

Good clarification.
