Thanks. I got 99% of it out after some scraping and chucking a cleaning bore brush into my cordless drill....not ideal I know but it seems to have worked.Alloy can play into how the crimp works out. Some manufacturers run softer alloys figuring that the coating will make up for it. In a lot of cases it does.
I’m also wondering if the coating is softer. I’m worked with powder coated bullets before and that stuff can be super soft. You can scrape it off with your fingernail. The hi-tek is hard as woodpecker lips.
I have some mercury from some old thermostats that comes in handy when I have bad lead issues. Snag it when you see it!
Artie is spot in with the copper chore boy. Make sure the relay copper and not plated steel (magnet test) wrap that around a brush and get at it.
I'm almost wondering if this is a brass issue? I just spent the last hour inspecting 600+ rounds and the majority of them didn't have any lead slivers at the casemouth. If I wasn't expanding the casemouths enough then why did ~400 of them not have any lead slivers? Or maybe the overall length of the brass varied enough that some were expanding more than others?
Never had this problem with the tens of thousands of blue bullets I reloaded. They use a polymer coating and are 0.355"
In any event I have a bunch to pull. Sucks that I can't use the hornady cam lock puller so I can easily dump out the powder. I hate wasting powder. Got 2k blue bullets on hand that I'll use.
I think Acme uses HiTek coatings according to an article I read:
"Acme Bullet Company itself labels them as “Lipstick” Bullets due to the bright red coating. This is a HiTek coating applied to cast bullets of a 92-6-2 alloy with the 92 representing 92 percent lead and the others tin and antimony. Acme says the coating is bonded to the bullet on a molecular level and completely encapsulates it"
I'll definitely grab a chore bore too for future use.
