I'm curious Marshall. Could your .377 250gr bullet be cast with a larger meplat? Or would this present feeding problems from tube mag rifles? I notice that the .458 rifle bullet has a meplat that's about 70% of the nominal diameter and the .429 bullet has about 80%. The .377 only is about 65%. These bullets are all regularly fired in various Marlin 336-styled rifles. Since killing power with hard cast is highly dependent on meplat diameter it would seem like a good idea to maximize it. How far off base am I here?
