Sierra 105gr Blitzking data

[cceckhoff58]

The Sierra BK is performing great for BR shooting under my conditions. I load them with 26.0 gr of N133, velocity is 2550. Barrel is a 22 inch PacNor, 9 twist, 3 groove. I recently shot 16 5-shot groups at 200 yards. These were all the same rounds. Nine groups were 20-32 mm - small enough for every POI to hit a one-inch 10 ring. Of the other seven groups none was larger than 56 mm, just over 2 inches.
