Great thread! I’ve got some 280gr A-frames I want to work up a load for as well as the 250gr AF. I have “all” powders so I can go to “THE” powder, whatever it is. CFE?…
Using CFE223 in my 35 Whelen I can safely get a chronographed max of 2,690fps with the 275gn Woodleigh PPSP with out any pressure signs. I backed off a little bit and settled on 2,600fps as my working load. That is in a 25 inch 1 in 12 stainless steel barrel.
With careful loading you should be able to get that or close to it depending on barrel length.
