H4895 with 69 Sierra’s is the cats ass! Works fine with 77’s as well. I was using 23.5grs with the 69 Sierra’s.
I have never had luck with 4895 in our tubes. Always reached pressure before any top speed. Although it was accurate, it was slow as all get out. Both versions. I/H. And since AA is off my list...
Good luck though and if I was in the need for powder, a slow load is better than no load
