Finally got to the range. And chronoed both guns.

The 30-06 was shooting Average of ten rounds at. 2813. The shots in order are. 2807 2817 2817 2817 and 2806. That is a high to low difference of only 11 feet per second. Not sure how to calculate SD.

The 270 wsm five shots in order were. 2940 2952 2966 2949 and 2977. High to low difference of 37 feet per second still would like to know the standard deviation. By the way that was with a 150 grain ballistic tips seated to the lands with 67 grains of magpro.

I will look through the whole thread and I will pm the winner of the bullets I promised.
