This morning it was 34° when shooting commenced. The good thing --- the breeze was light. Bad thing --- it was inconsistent.
Powder charge was reduced to 115 grain Blackhorn down from 120 grain previous shooting. This was done because the primers showed some leakage through.
Breech plug was changed from Knight plug to Lehigh plug. The primer seal was made in the Knight plug by using an o-ring. Primer seal in the Lehigh plug was done using 0.013" of shim.
Vent liner was changed to Lehigh vent liner from home made vent liner.
Primer was changed from Federal 209A to Winchester W209; the W209 fit the Lehigh plug better.
Shooting began from a clean cold barrel. Loading and shooting was done without swabbing. Loading and shooting was done without waiting between shots; without hurrying. Ten shots made at the lower target.
It was quite nice that the first shot, was not wild high. It was nice the first shot, and last shot landed 1½" center to center.
This combination would be taken hunting, if season began tomorrow morning.
This probably concludes shooting the 250g Fury Star Tip at paper, until October. Alas the scope will need to be switched to the 1X.
