More than 30 years ago I had a 25-06 and used H870, still have half a lb. I have a little data, and wonder if there is a correlation between that and the WC867 I got a few years ago. I know they are very slow powders.

My pastor recently discovered the rifle that has been in his attic in a case for the past 30+ years was a 25-06 - Winchester Model 70 no less. I had planned to experiment with the 867 when I get my 25 Krag AI barrel. I really don't want to experiment with his rifle, though.
