I bought this single cavity mold on ebay years ago. I never used it. I was playing around last night and cast a bunch of these. I picked twelve of the best ones and sized/lubed them. I noticed that the forward band is slightly smaller in diameter that the rest. Hmmmmmm. Could it be an issue? Maybe. Does anyone have any experience with this bullet. Please comment if you have.

If someone else had of done to me what I did to myself . . . I'd have killed him. Humility is an asset. Heh - heh.

I've had wonderful accuracy with the 429215 and 429244 Thompson designed bullets.I think the front wiper band being smaller helps it enter the forcing cone straighter. (just my theory and may be bunk,I dunno)

 

I think one of Mike Venterino's first published articles over 40 years ago was about using the 44 Thompson bullets and I'd what lead me to the design.

Shot this bullet extensively in both Marlin 1894 .44 Magnum rifles three decades ago with good results.

Hercules (then) 2400 powder and wheelweight alloy Dropped at .430+ from the mold, sized .431 simply to lube.

These rifles were the early ones with 1 in 38" twist requiring a lighter bullet for stabilization.

I have found the 429215 design with a gas check installed to  be very accurate in all of my .44 mag revolvers and my Winchester and Rossi rifles.
