Braved the 33 degree temps today and took the 1 in 7 twist for a spin.
240 SMK, 8.5 VVN110, OAL: 2.25"
1022
1018
1001
1022
I loaded 5, but the gas port was still in the "Super" position for the first shot, and it didn't even hit paper. The remaining 4 made a 1.25" group, but still are not stable.
220 Sierra Pro-hunters are also not stabilizing, though I loaded them a bit light and ended up with 800 fps velocity. I'll try getting them to 1000 fps and see if it makes a difference.
I also loaded some pulled surplus 175 SMK's to ~1040 fps, and they appear to be stable.
This is driving me crazy! I'm waiting on my local dealer to pick up some AA1680, which I should have by this time next week. Until then, I guess I'll just continue to shoot supersonics in the hope that the barrel just needs to be broken in.
