so with the early data plus the last ladder,
i shot 5 three shot groups. each was .005 shorter
than the prior starting with an at the lands number.
used the powder load that looked best without pressure.
in the end .010 and .015 off shot best, but .015 showed a little pressure
as it had more bullet in the case.
so next up is to shoot those 2 with 5 shot groups, plus maybe some with a 1/10 or 2 less
powder, again because of more bullet in the case.
