Don't know where to go with this question, so; I'm trying to use up some old reloading stock that I've had for 40+ years. One such item is a 1,000 240grn cast SWC's sold by Denver Bullets out of Wheat Ridge, CO. Problem I'm having is by the time I seat them in trimmed to length cases to the max oal, they are too far inserted into said cases to properly crimp the case mouth into the forward crimping groove. I'm not looking for a solution as there really is none for my purposes, but am mostly wondering if anyone knows the mold they most likely were cast from and what their original intended purpose might have been. I don't need much of a crimp for a tube magazine rifle but can't seat them out too far and expect them to feed. On the other hand, depending on cylinder length an overly long seated length with a proper crimp would work in a revolver. Not exactly a dual purpose loading, though. Back to my question; anybody remember Denver Bullet Co. and this particular bullet?
