A little different critter. It was the 190 Hornady btsp in a 22 inch Winchester 670 a few years ago.
11-21-1995 50 degrees ambient 30-06 190 Hornady btsp
63 gr H4831 2681 fps
64 gr H4831 2775 fps
65 gr H4831 2816 fps
I used the 63 gr load for a couple years. Two boxes of bullets at 100 each. It gave very good accuracy. The rifle darn near killed on both ends.
I also tried IMR 4831. It started showing pressure signs as it approached 2800 fps. H4831 was much more forgiving.
did you use lapua or norma brass. thank you for your experience and information. Ron
