It's actually the new 123 AH bullet. Since our cartridges have a different capacity my loads are meaningless. There is a tread on the new hammer with a spread sheet link that people are listing their loads. There are some prc loads on there. The powder that worked the best is h100v. But several powders got me to 3500 or just under.
I have two Kimbers chambered for 7WSM - one for me and one for one of my sons so could use some more Win brass for our 7WSM’s. What would you be asking for any extra brass you that you are interested in selling? Jim Billman
