So I saw this thread a few months ago and thought I'd give it a try.
Here is what my progress looks like. I start with a fired case and fill it with lead. Using a lathe, I remove the lead back to the rim of the case. Then I drill a 1/4 hole approx .2" deep in the bullet to allow for some "squish" when I form the nose. The finished product is last.

I made me a steel die to use to form the nose. An 82 degree countersink provided the needed angle, it seems to be pretty consistent and works well. It really crimps the lead in place and gives me a nice hollow point.

Here's the finished product. There seems to be some variables like case manufacture that I haven't taken into account, but all the bullets weigh from 262 gr. to 272 gr. I'm happy with my first try.

Now, I ask you. What powder charge do I use to load these up and try em. I realize this is uncharted territory, but at one time everything was uncharted territory.
I've got some BlueDot and I've read that it can be downloaded a bit without any of the problems associated with powders like H-110. I was thinking along the lines of 11.0 gr. of BlueDot. Although I don't have any Unique, I've heard it's a very friendly powder.
Anybody have any ideas. I don't want to hot rod, just shoot em to see how well they hold together.
