Default TC Black Diamond, Sub-Bases And Maxi Balls

Mountain Devil kindly sent me some sub-bases for my experiments. Last time i did this the gun was my TC Encore. It did pretty good with the sub-bases behind 320 grain Maxi Balls.

Today i took my TC Black Diamond to the range. Fired some 320 Maxi Balls in front of the sub-bases. The powder charge was 80 measured grains of sifted 3F Goex Pinnacle. The Black Diamond did not like the combination at all. At 75 yards the three shot group was over 5".

Thought something might be haywire with the scope or mount so i fired a three shot group using 100 grains of sifted 3F Goex Pinnacle, a crush rib sabot and the 250 grain SST bullet. The three shot group measured about .75". It ain't the gun or scope.

This experiment will continue. Next time i'll take the Encore.
