H1000 shot tiny in this barrel too, but after it broke in I could not get to the high node anymore. Had to shoot the next node down in the low 2900s.

The next day 82.3 .050 off repeated for a 3" and a 4". So I have been doing cold bore testing now that Im confident in the load. The last 2 mornings I have shot one 3 shot group cold bore from a fouled barrel. I will keep doing this until I get a little more data to be sure that it repeats. Velocity spread have been around 10 fps for the first 3. Yesterday was a little windy so the group was 4" wide but under 2.5" of vertical (black marker group, I reuse the targets for other rifles too.) today was a head wind and shot about 3" tall.
