    MP 432256 aka H&G 503 Clone

    If you PM Miha he might have one left. He just did a run of both Solid and Hollow Point. http://castboolits.gunloads.com/show...-Clone-432-250

    There is some history in the new Handloader Magazine. This was the last "Keith" Elmer designed and it was after the 44 Magnum was an established cartridge.

    Either one, I've used both, if it's a factory mold you're after. If your economy allows then the MP as stated or Tom at Accurate molds. He'll make it to fit your guns throat if that's an issue.

    I have both and they are great. I usually cast the Lyman since it's a 4-cavity.

    RCBS makes quality moulds most of the time. If not, they will make it good. I hear the Lyman version has undersize front scraper band. Accurate molds are expensive, but verygood quality.

    If you can get the MP 503 clone, do it. If not, the other two are
    wonderful molds, but I'd probably rate the RCBS a bit better
    mold quality and durability than the Lyman.

    NO bad answers to this question.

    The RCBS mold design, is supposedly truer to the original Keith design than the current Lyman offering. I believe it has something to do with the driving band width and the shape of the bottom of the grease groove.

    What Bill said, exactly. If I had to buy one, it'd be the RCBS. Mike

    Concur with the choice of RCBS. In my experience the RCBS molds cast more easily.

    I've had great work from my Lyman #429421. My RCBS moulds are all a delight to use, also--though a couple run a few ticks undersized. Tough choice. Tom's Accurate Molds have been a cut above both, though--and if your revolver runs with wider throats (SAAMI spec is .433") then Tom's tools or a Mountain Molds semi-custom design might be a better idea. The cost of these small-shop tools is not significantly higher than that of the mass-produced products, and the tools are worth every cent of their prices.

    I would go for the Lyman because you can get it in a four cavity.

    If you are shooting a revolver with larger throats you should talk to Tom.

    I have (deep breath): a 1-C Lyman 429421-round lube groove-248 gr., a Lyman 2-C Lyman 429421-square lube groove-250 gr., another 2-C Lyman 429421-square lube groove-250 gr., an 4-C NOE 429421-square lube groove- 260 gr., A 2-C MiHec/Miha 429421HP-square lube groove- weight of solid as yet unknown, and a 2-C RCBS 44-250KT-square lube groove- 260 gr. All the aforementioned weights are as-cast with WW's. I plink and target shoot with the NOE and hunt with the RCBS (2 deer with it this season so far). I'd have to go with the RCBS although I must say the MiHec appears to be very similar to the RCBS. I really like the nice fat front driving band on the RCBS bullet.

    Why is the H&G 503 clone better than either the Lyman 429421 or the RCBS 44-250K? I am not talking quality or stuff like custom diameters. I am just talking design. When I look at the 503 it seems an awful lot like every other SWC. It seems to have a straight angled side as opposed to a radius or compound radius to the nose. The meplat seems similar. Weights are about the same. All are plain base.
