    Rich, I forgot to mention my SS is 24" + brake. I wanted a bit lighter rig so I went with 2B contours and could only find 24 inchers.

    Shooting Lance's H1000 dope I wasn't getting near his velocity and I went 1.5 gr higher. Maybe it's the barrel with only 58 rds thru it and 2" less. Time will tell, I guess.

    Probably 25'/Inch I'd guess. N565 is working well for me in the sst. I never did get as much out of H1000 as several other powders.

    I'll get some, but not sure I'll have time to get load finished in time to head to the mountains. ( 2 weeks, just maybe ).

    I switched to RL23 w. 156s in my 26" 1:7.5" 6.5SS, still only 74 rounds down the barrel, but hit 3078fps into one of the 3 best groups I have ever shot (which I might never do again). Once it cools down in Phoenix, I will be testing some RL26 for winter hunts.

    Lance, I was 200 fps behind you with 1.5 grs. more than your load with no pressure. 24" barrel and 50 rds fired. Going to add 50 rds to barrel and then try something different. Also maybe just different lot #.

    Won’t be hard to load for with n565. You will find nodes all over the place

    Berger twist cal. claims you need 1-7.5 min rate, but your groups look good.
