Ya, that looks pretty good. I wonder if I could get it to feed though in my Puma 92 454. The metplat looks a little fatter then the CP 360 gr and I think the bullet profile makes a difference in the little kitty. It sure would be a good thumper in the Redhawk though. I'm getting 1155fps with H110 and CP 360gr out if the 4 inch barrel. Should be good bear medicine if needed.
I just checked CP and the 360 WLN is "nose .390 meplat .355" according to CP. Yours just might feed in the levergun. Would you be willing sell me a few lubed with the gc to try out in my levergun? Shoot me a pm if you're willing. If they worked out I'd get the mould specs from you and just order one up.
