I was in on the 311299 GB from NOE earlier this year. I spent quite a bit of time tinkering with the HP cavity until I got boolits I was happy with. Intended use for this mold is ringing steel and hunting deer with the HP version out of my 308 Win or .30-06. I cast up some test projectiles from Lyman #2, 50/50 Pb/COWW, and Dental X-ray lead, just to see what would happen, all air-cooled. My test media wasn't ideal, but it was what I had available at the time - gallon milk jugs filled with water. I loaded all of them in my .308 Win PBR XP with 16 gr. 2400 behind them, a general accuracy load, not blazing speed. First five shots went into less than 1" at 100 yds, very pleased, ready to shoot jugs! Lyman #2 was up first, I had 5 gallon milk jugs back to back and it wasn't enough, the bullet slipped through the last one. I lined them up again because I shot high on the jugs just for this reason. I added two quart oil bottles behind, hurried back to the bench and fired again. Recovered the boolit! 45% weight retention, 5 milk jugs and two quart oil bottles. Sheared off the HP'd portion and a little bit more. I shot the second line of jugs with the 50/50 mix, penetrated into the 6th gallon milk jug, 65% retention, nice mushroom on the shank portion of the boolit. Third line of jugs was the x-ray lead, the boolit looked identical to the 50/50 boolit after stopping in the 6th jug again and retaining 64% of the weight. I know this wasn't an ideal test, but I was very pleased with the results, I'm gathering newspapers to fill a plastic-bag-lined box and soak with water for a little better test media. These are the first loads I've shot from this mold, they cast .3005-.301" on the nose and .311" on the bands - perfect for my .308 and .30-06 bores, the nose just engraves at the muzzle. I'll post pics later, I need to hit the road.

What are you sizing them to ? I have a Lyman 311299 with a hp but have not been able to test them out yet.

Lubed with homemade concoction of speed green, zero leading, just a lead "wash". I cleaned the bore for the first time after several hundred rounds, just gray wash, no shiny flecks on the patches.

selmerfan: what was the velocity or best guess with the 16 gr of 2400?

Were all of your test shots with HP'd Boolits? or were there any with solids?

All were shot with HP's. I'm guessing around 1600 fps for velocity, but my chrony is down and out until I get funds for one without a bullet hole in it... :grin:

The hole definately affects the accuracy.

Yes, and the aesthetics. Plus it's not edible...
