This is how I cast my GB's, I did this in my dorm room a few weeks back. This bullet is for my 1911 45 ACP, mold is a Lee Double Caivty RNFP 255gr lead bullet, glue cast they weigh 20grs.
1. Lube the mold cavity, I used vegatable oil applied with a tooth brush, very light coat this was all we had in our room.
2. With open spur plate shot the cavity full of glue.
3. Turn and put the mold in the freezer right away
4. Take the mold out after about a minute
5. Pop open the mold bullets fall right out because of the oil
6. Repeat.
7. As the mold is in the freezer, I took a utility knife and cut off base at the last lube band.
8. Leave them out for an hour on the country to harden up completely.
Case Prep.
1. Pick out 50 or so cases, mark the case head with a black marker to set them apart.
2. Drill out primer pockets to 1/8"
3. Prime Case, I am using Magnum Large Rifle Primers because we had 2 packs under the bench and no other reason to use them
4. Either hand seat the GB with finger pressure, or just set up your die in your press and seat them like a normal bullet.
This is my method, it works for me, when shooting a GB make sure there is a light coat of gun oil/lube so the GB doesnt get stuck in the barrel, happened to me with my dads Ruger, punched the bullet out without a problem, I have yet to have a problem with my 1911 and suspect I will not.
6 paces in my garage 10 shots

Again these are not toys, I posted this picture a month or so ago when I first started playing with them, it is GRAPHIC/BLOODY, shots were first 5 to 6 yards, after animal was dead I tried point blank just to see GB did punch a hole in his side.

This was with just primers, no powder, 2 shots in the dome an it was lights out on this guy.
Tomorrow I will try a rifle bullet. I wish I had my Savage 340 30-30 in working condition right now would be perfect for this test. Has anyone tried to seat a gas check yet on a GB?
