Thanks, Uncle Nick- Already did that, and for the 22-250 the loads are only different by 0.1 grains. Will start with min loads and work up. I seldom shoot the max load of anything. Groups size (after a fairly moderate velocity for a given cartridge is obtained) is the maiin objective for me. Since Varget is unobtainable right now, and the load data shows the 204 Ruger with Berger bullets and H4895 as comprable to Varget, it makes sense to me to waste a few rounds seeing if the old powder will work at this time. Besides, I like using old Grampa Horace's stuff. I think it would make him smile. Makes me smile.
Really appreciate evryone's opnions and thoughts.
