I often grumble about the dumb designs that come my way, so it's only fair that I also give credit when a customer makes good choices.
Here is what appears to be a bullet for the Marlin 444. It is very similar to the proven Fryxell design except it is heavier -- and heavier is usually better, from the cast bullet's point of view, anyway.
What I like about this:
-- we expect this bullet to feed and chamber in the 444's micro-throat because it has the proven Fryxell nose. (0.425" front band, 0.315" nose length, and 73% meplat).
-- the two large body bands fill out very easily (that said, I personally would opt for numerous smaller bands and live with the fill problems. Do as I say, not as I do
-- the alloy is wheelweight and the block is aluminum, my favorite combination for heavy big bore bullets.
-- this mold was easy to cast with and produced consistent diameters. See the previous comment on wheelweight and aluminum.
-- note that it was not necessary to add tin or, heaven forbid, linotype. The richer alloys would only serve to cause shrunken spots, stick to the bottom of the sprue plate, and take longer for the sprue to harden. Wheelweight rocks.
Here are the design details, except the block was actually the standard 2-cavity, not the XL as shown on this design page.
