Working up a new load
I thought this was a great thread and so after being at the range on Wednesday working up some new loads, I thought I would post this scan.
Shot it with a stock Browning A-bolt in 7mm with Barnes 160 TSX at 100 yards with IMR 7828. Don't have a picture of the rifle now, but was off a bench with bags at front and rear. The two upper targets were without a hold on the fore stock just to see the dispersion in the group, and the lower with a proper hold of my one hand on the fore stock. Just working up the load so maybe some tweaking is possible with LOA. Wind was strong, so there is one flier.
I used a program called "on Target" to measure the group instead of calipers. This way I can keep the scanned version without needing the paper copy. Measurement of center to center is 0.447 moa or 0.468".
