..and pretty much the same tuning has been working. I didn't sleeve the valve on the rifle, hoped the long barrel could use the "extra" gas and wanted higher energy.
Keeping the same 3% requirement, and also looking for 300foot pounds per 12gr., ended up with 34 shots / 10.3gr. / 610fps...which works out to about 290 foot pounds per 12gr. Will work on that as the weather warms (thinking for this one, 30 shots at 10 foot pounds would be useful).
