Fellas, I have a couple of 429360 moulds, a 1-cav. and a 4-cav. Just read Beagle's unflattering article on it at castpics, and though I've never cast any bullets with these moulds or shot them, I got the bright idea (well, an idea anyway) that maybe I could take the 1-cav. and have someone cut the diameter of all bands to cast a .431" bullet for my new Marlin .44, as Beagle did with his, but ALSO - and here's where I leave Beagle's work with his mould and (maybe???) break new ground. What I'd like to do after reaming the bands out to cast at .431", I'd also like to convert the mould to a RNFP configuration in front of the .431" bearing surfaces. What do you guys who make your own moulds know about what can/might be done to bring this idea to fruition? I know just enough about lathe work to know I need some MUCH more knowledgeable folk to advise me on this. I think I'd like to keep the big flat on the nose of the 429360 and just have an arc from the front of the bearing surface to the edge of the nose flat, probably a tangential cut. Who could maybe do these cuts on my mould??? (if anyone?)
Also, does anyone wish to venture a guess as to what it might shoot like? I tend to be a bit demanding of my expectations of my moulds, and the accuracy they'll produce, even if my ability to shoot isn't what it used to be, and my eyesight surely isn't as acute as it once was. I've been considering the Saeco 265 gr. RNFP mould for quite a while, and I think this would likely produce a similar bullet (probably with a larger flat on the nose) that should feed well in my Marlin 1894. Anyone think they've got a real clue how it'd shoot? Just mulling the idea at present, so any input is appreciated.
