This is one of those "I needed to make something, so I'm writing about it" posts.
Die in question: Lee bullet-seating die for .30-06.
If you'll look at the pic below, you'll notice that the inside of the die body is hollow in the lower section, top section is threaded inside, and in between
Normal use, no problem. Start messing with larger-than-standard and short bullets, like the .32-caliber pistol stuff I've been using for light loads, two problems:
First, those larger-diameter bullets* don't want to fit through the hole well; they tend to get slightly stuck, which causes from annoyance all the way up to "BLEEP-DAMMIT!"
Second, those wadcutters? That seating plug cannot seat them as far down as needed. Which necessitated some squirreling-around with a different cartridge die to seat them.
Yes, you could drill the hole out a bit. This being a heat-treated die, I kind of hate to start trying that. Plus if you do that, the seating plug will fall through. So what you need a different seating plug.
So I hied myself off to the lathe, and finally produced these:
I could probably use aluminum for both. I was worried that, with the hollow-ended one, thin as the walls would be toward the mouth, aluminum might wind up being expanded a bit with some bullets; so flat-face for the wadcutters and such, steel for the other.
Making the hole was fun. Wound up facing-off the end so it'd be flat and square, which also marks the center nicely. Centerpunch to set that spot. then use the drill press do drill in about 3/8"(actually a bit more, ought to measure it). Back to the lathe, adjust the compound rest, which both slides back & forth and holds the tool post which holds the cutting bits, to a very shallow angle, and used a bit I'd ground long and thin for a different project a while back. Move the bit well into the hole, move it toward me until it contacts the inside, then back it out at an angle so it cuts the hole into a tapered shape with a few passes. Yes, sounds kind of confusing, I'll try to take a picture later so I can label all this.
Anyway, it solves the problem. And I now have some more test ammo loaded. Which may take a while to use, as it's misting outside; supposed to stay above freezing tonight(hope they're right), if it does may be able to shoot tomorrow. If can't then, Wednesday is going to suck(snow and sleet) so it'll be sometime after that.
*This also occurs with some normal size(150-grain and up) cast bullets sized .311"
