The reduced load I`m using for my vintage sxs is with IMR PB. The psi is around 5,900. I`m wondering if I could use that data and just work up a wad column with the op card,fibre wads and os card. I know loads for the Magtech brass shells tells you use blackpowder only but their has some to be some smokeless data out there for this brass. I hate buying RMC brass at $6.00 a shell but it is rated for smokeless and you can find data.

God bless the fine men and women in the U.S. military
