IIRC the lowest was 1388 and the highest around 1510 or so (this is from memory but I did post the results here at the time).

Nonetheless, I would use that load without question.

ETA---looked it up and the low was 1388 and the high was 1542 for an extreme spread of 154fps! I was correct about the average velocity though of 1452.
That is my issue w/ many ammo manuf numbers. They get one gun to read a high vel & then post that as the ammo's vel. BS for the most part. It should always be an average & come from at least 3 duff guns. Then I might start believing them.
"Given adequate penetration, a larger diameter bullet will have an edge in wounding effectiveness. It will damage a blood vessel the smaller projectile barely misses. The larger permanent cavity may lead to faster blood loss. Although such an edge clearly exists, its significance cannot be quantified".
