    I've come into probably 700-1000 (literally) cast lead bullets that are .429 and .431 diameter. Most are already lubed and gas checked, various weights also. I load a lot of 9mm, 45acp, and rifle calibers but have never loaded this caliber.

    My questions are:

    These are for 44 mag correct?
    Why would I use the .429 instead of .431 and vice versa?
    I don't own a firearm that shoots this caliber, what would be a good platform to start with? Probably for target shooting and deer/hog hunting. Ruger blackhawk/redhawk?

    Looks like all I need to get started is a firearm, some brass and a set of dies.

    Any input would be appreciated.

    These are for .44 guns (44 russian, special, magnum).

    Although 430 is the accepted minimum size for a cast bullet, I suppose .429's might be desirable if you had a really tight cylinder. In theory, the bullets should be .0005 or so over the throat which should about the same over the forcing cone/bore.

    If they are very hard, you may get leading from the .429's. They won't be able to bump up to fill a loose gun.

    I like Rugers.

    The 44-40 uses .427" bullets or sometimes slightly larger. The bore of the firearm is slugged to find the correct diameter to use with a cast bullet. Lyman suggests a bullet diameter of .001" over groove diameter. For 44 mag. a .430" cast bullet works well for me.

    Sounds like some shootin in the near future!!

    In my 44s i size everything in a .430 die & the boolits usually spring back to close to .431 depending on alloy used.
