I'd like to get a mold made to cast a .452 hollow point identical to the T/C Cheap Shot. I've tried using pure lead .44 and .45's in sabots in my Black Diamond XR , but recovered bullets show fins corresponding to the slots in the sabot petals.I found a 300 gr Lee .452 soup can with fins that measure .478! Accuracy was poor, about 4 inch 3 shot groups at 100 yards. Factory Cheap shots do not do this so I suspect they are not " pure " lead but some alloy. Recovered specimens , from both dirt and game show that expansion is violent and the nose of the bullet is gone with a small portion of the shank left. I limit my velocities to 1600 fps and was wondering what the best alloy would be and if expansion and weight retention would be adequate if the hp was eliminated. Also , who makes good durable custom molds? I'd like a single cavity to cast smooth sided . 452's in 250 and 300 grain. Thanks for the help!
