Who's gunna figure this one out?

I've had this mould for ages, don't know for sure when or where I got it.

Today I decided to cast a few of them. I did not want or need many, just a few to play with. Cast about 80 of them.

This is where it starts getting a bit interesting. The bullet drops from the mould at 260 grains with my alloy. Sized, checked and lubed is about 270 grains. The front drive band is about .450-.451, I think pretty common for Ray Thompson's designs to have an under sized front drive band. I think his theory was easier alignment going into the barrel. The main drive bands are just barely .452.

These will be shot in the 455 GNR and compared to Elmer's 454424 and some LBT LFN's.
