44 Mag bullet sizing

[Larrymcc1]

I have been casting and loading for quite a few years and now will be casting bullets for my .44 Mag revolvers. I just bought two separate molds. A Lyman 245 Grain SWC, and a 6 gang Lee .44 Mag mold .429 Diameter 240 Grain SWC. I was reading one of my old Ken Waters Pet Loads he advised they should be sized at .429, looking at mu other reloading manuals they show the bullets at .430 diameter. Any advice will be appreciated. Thanks in advance.

Slug your chamber (cylinder) throats and size the bullets to the largest one. Hopefully, they will all be close to the same.
Ideally, you can just push the bullets through the chamber throats by hand.

Larry,

I've been using a .430 sizer with complete satisfaction.

I use cast lead 240gr SWC sized to .430 and they do not lead up. Even with 19.5gr of 2400 behind them in both my 29-2 and my 629-6.
