Winchester 780 Supreem.

Anybody using 780? I was think about trying it in my Ruger 77, 25-06. The only Winchester powder that I ever used is 748 and it shoots and meters great for one of my 308's.

Years ago, when IRM introduced 7828, I tried it in a 25-06. Working up a load, shooting over a chronograph, the velocity increased as I went up incrimentally up to a certain point. When I reached this point, velocities went wild, with over 100 fps swings between shots. I decided that 7828 would be great for a BIG bore magnum, but not for the 25-06.
Without trying 780, I suspect that 760 is a much better suited powder for the 25-06.
If you decide to experiment with 780, use a chronograph to verify the results you get.
Never loaded for the 25-06, but seems like a good powder to me. Not sure how temp sensitive. As good as W760, just slower burn rate. And gets good velocity.
