Yes I have and it is .432. I have tried 240g in .431 laser cast and 250gc in .432 Beartooth. As I said the light loads in the laser cast get my hops up except that there almost always seems to be the occasional flyer, usually to the up and left of about 6 at 50 yards. While I dont feel that these results from a pull off this could be what is happening. Not that I am above pulling off target, but I am usually aware when it happens. I havent tried the Beartooth .432 with a light load yet but as I now have lots of empty 44s I will give that a try. While 240 cast light loads are listed in several of my manuals I dont find much in a light-loaded 250 cast, at least in powders that I have. How many g of AA#2 should be used or another powder in that range?? I will probably load about a half box of each and give each a real good workout. As all I am wanting to do with this barrel is have a good time punching paper, if these loads don't pan out I might give something in 200g a try.
