[QUOTE="cornchuck, post: 3021506, member: 20220"] ....check case mouths if you haven't trimmed them for a while. When I trim my cases, I trim them to max trim length. So when I started to reload for my 300 PRC last year, I bought new (100) Lapua brass. Right now I am on the 7th loading. I prepped them for this loading and about half them needed trimmed. Trimmed, primed, and poured the powder. Went to seat the bullets and started with the ones I trimmed. Got into the untrimmed and things got weird. Bullets got harder to seat and a couple I pushed the neck into the case body. I got mad. What was going on? I never had a problem before with any of my guns I reload for. Got to looking at my seating die, Hornady Match Grade. It has a ring in the bullet sleeve the case neck hits. My Redding Competition dies doesn't. Then I started to look at my cases. I noticed the case mouths had a burr on the outside. When I got this batch of cases, I went through the whole case prep. Full length sized, trimmed if needed, flash hole uniformed, primer pocket uniformed, deburred inside and out the mouths. I deburred and reamed the cases and everything was back to normal. So the moral of the story is, check the case mouths for a burr if they haven't been deburred for a few loadings. Jason [/QUOTE]
