Home Forums Reloading Bullet Casting Modifying the lee 44mag 310 mold

I have this exact mold in a six cavity,load it in my 44 and 444 its a real hammer in both loadings! IMO rather than risk the chance of screwing it up [centering as was previously pointed out] have a custom cut with similar specs and sell your gas check... would probably be less of a hassle in the long run.

Lee 429-200-RF is a fine plinking bullet from any 44. Cast mine from wheelweights, tumble lube, shoot unsized in several 44s over Trail Boss or Unique. Simple and 6 will go in 3" @ 25 yds with "hands on the bench". Never lead a bit. 6 gr trailboss gives a tad under 900 fps in the 44 magnum.

Lee molds are so inexpensive, I doubt remachining yours is worth the effort.

Cheaper than 22 RF at today's prices.

That Lee 358 158 is a great bullet. Started with a 2-cav, and eventually got the 6, because it shot so well in handgun and lever gun.

Same with the Lee 430 310. Mine cast right at 300 naked, and shoot very well as a plain base with mild loads around 1000fps in my 10" contender. I shoot them hot with H110 in my Marlin with a gc, and they are moa at 100. Most accurate bullet I shoot in the lever gun.

I started with Lee moulds because they were so inexpensive, an I figured I'd ruin a few learning the ropes, but the designs have shot great in every cal so far, and the dozen moulds I own are Lee.

I have done it with a Lee 458 mold. Just stuck it in a milling machine and cut it down to where I wanted it then drilled and tapped the hold deeper for the spru cutter screw.
