Just as I thought. You haven’t a clue about reloading.
Dude, you missed the point. Reread the whole thing in context. It was a joke. Did you miss all the ‘smileys’ ?
I just got a catalog from Sportsman’s guide. One item that I’d not seen before was a device for making rounds loaded with FMJ bullets into rounds loaded with hollow points. Seems to me you could use that, fill the cavity with the substance of your choice, and then seal the tip with a polymer of some sort. Probably could use silicone caulk in a pinch.
