It would take serious laboratory testing to make such a determination. We felt that it would make little difference in the research because the net results should be about the same. Misfires were calculated in three groups, with 432 rounds in each group. The high deviation in the earlier years is unacceptable for target practice, personal defense or hunting purposes. This makes these rounds unacceptable for practical use.
Most people buy their ammunition in individual boxes.
The average sale is about 1 to 5 boxes at a time. Annual average purchases could be as high as 1000 rounds or more. The velocity, of a bullet has the most impact on the trajectory of any given bullet. As a general statement, the higher the velocity the flatter is the trajectory. In other words, the drop of the bullet is lessened as a function of range with higher velocity.
