Anybody had any luck with NOE 432-200? I have to have a bullet that fits the .430 bore of my rifle. I've been shooting a hardcast bevel base .430 cowboy action bullet but the dispersion is more than I can stand. I am also considering 432-265 SWC. Any advice?

Sorry for the late reply. I just read this post.
I have the same rifle /caliber combination. I also ran into accuracy trouble with hard cast bevel based bullets.
Since it is 44wcf (44-40) any safe loads you fire in that rifle will be low pressure. Pressure that is too low to properly obtruate a hard cast bullet.
Properly sized .430 bullets cast from 20-1 or softer alloy will make a world of difference. Plain base is even better.
I didn't look at the mold you referred to. If you are going to cast use 20-1, 30-1 or even 40-1 alloy and a soft lube.
If you are not committed to casting yet, try some 200gr . 430 bullets from Desperado Cowboy
Bullets.
For a heavy bullet that is both a thumper and safe load try the following. From Desperado Cowboy Bullets, a 240gr . 430 and Reloader 7.
About 1350fps from my 24" barrel and black powder pressure. ( google that load or P. M. me if you want).
