Retumbo works great in my STW. 175 E-eldx @ 3160 bullets usually touching. Almost out of Retumbo. I picked up a pound of US869 to try. Anyone with experience with this powder? I assume it work well with heavier bullets. I also wouldn’t mind trying it in my 300rum. Any info would be appreciated.

The tightest group I ever shot at 500 yds was with 869 on a cold December day. Shot the same loads at 90 degrees and the group went way south. Unstable!
