Scott, your 2774 figure agrees with Quickload for 23.6 grs of TAC, in a 20" barrel (2751 using 2.260 OAL. In order to get 2900 you need to used (according to the calculation Quickload does) a barrel of 26 inches.

That could be why I never got TAC to shoot real well, I was testing at around 25 grains and never got down that low.

Well now, it's a done deal.

Just got back from the range where I fired a 5 shot group at 100 with the Black Hills 68's. Fired another 5 shot group right on top of the first group with a handload of Hornady 68's and 23.6 Tac. All in just under one MOA.
