We decided to try a lands test with H4831SC, We looked at the OCW test again and decided to try 42.8 with multiple lands tests and of course tried 42.5 again because of the original .39 moa group

Three round groups Lands testing

We tried 42.5 grains at .015 jump, it shot .505 moa
and 42.8 just didn't seem to work
.015 .95 moa
.021 1.10
.026 .912
.040 .88
.060 .858
.080 .67

Not impressed, still nothing was working
