Thank you. That helps a lot!!!

Fulton has the three of them for 99 bucks. I'm not sure I want to drop that right now. So.... I see what you're saying about excessive pressure. But my thinking is if they have been shot a lot, there's more chance of it having a long headspace. But I guess that's probably not the big of a deal with a .30 carbine. Or would it be? I guess I was thinking it could create some gasses escaping out and being an issue.
