The old clock went blind; purchased a new one, and had to see how it worked. For the first shot, it was placed about 15' from the muzzle, and it read 1057 fps, so i figured it was far enough away, the sabot had already separated from the bullet. Moved the clock to 9' from the muzzle, and shot 16 shots shooting and reloading, shooting and reloading. Temperature was 50 at the start, and 54 when finished. What i wondered was if the clock would show me a difference between the Winchester W209 primer, and the Federal 209A primer. The rifle used was a Dream Season. The load was 105 grain Blackhorn. Sabot was black crush rib. Bullet was 300g XTP.











Kinda cool to have a clock with a memory, and not having to write anything down when shooting different loads.

Out of curiosity i had the machine eliminate the highest and lowest speeds of both primers, and recalculate average, and deviation.
