Not a bad idea, I imagine you would need a 50bmg though to have a large enough diameter.I did this once and ever since I've wanted to come up with a keychain casing punch
On another note I've been toying with the idea of a Casing Capper for home rolls but I don't have ammo knowledge to know where to begin. @Hopduro or @BrewinHooligan any ideas?
The 50 cal and 20mm would work perfectly for my lanceros.I have some 5.56 7.62 50 cal and 20mm round casings if you need any
I had this thought too, don't want to be ingesting lead if you can avoid it.Watch out for lead...might want to use new brass.
Most primers contain lead as well. Not worth the risk for me. I've had high lead levels in the past... now I try to make sure that doesn't happen again.If you load full metal jacket rounds, no lead containment.
