Ever notice how RN revolver bullets always seem to be among the most accurate? (I suspect that this is due to how the RN ogive mates up with the bevel cut on the forcing cone and lands, but that's another story). Anyway, while RN bullets tend to shoot very well, they are lousy killers at typical revolver velocities. As a result, I have long wanted to find a 429251 HP mould so that I could marry the accurate (and aerodynamic) RN ogive with the good killing properties of the cast HP. Well, I finally found such a mould. It was missing the HP pin, so I had to make one (.156" diameter at the mouth, 7.5 degree taper, extends down to the bottom of the forward driving band)
I just finished casting my first batch of bullets with the new mould. I cast them out of range scrap, which has a BHN of about 8 (similar to 30-1 alloy). The bullets drop from the blocks weighing about 242 grains. The base band is somewhat oversized (and not very round), but the body bands are pretty round and right at .430". The bullets size to .430" very nicely. I am going to load them to 1000, 1100, and 1200 fps in .44 Special cases and see how they expand.
