Nice post and great shooting. Looking at the ballistics info on Knight's website for this bullet, the energy at 200 yds using 120 grains of Triple 7 pellets, is about 740 ft/lbs. Is there a difference with the powder you used?
According to the same chart, using 120 grains of Blackhorn it is a little over 1,000 ft/lbs. Have you tried BH with this bullet?
The only difference is that I was using T7 loose powder. I have never found pellets to be as consistent as loose powder. If you were to weigh the individual pellets in a box I think you would understand.
I have used BH but because of the price per shot, I do not see enough advantage to make the switch. And do not get me wrong BH is a great powder.
This is a copy of a velocity comparison test I did between the two powders. I am shooting close to 3000 feet in elvation also so that will effect velocity somewhat. Ignore the line that says the sabot was a Blue 4050 sabot that is an error from the previous test using a 45 cal rifle. I will throw in the same typ of chart that I did for a 45 cal gun also. It is actually more complete than is the 50 Chart
This ballistic sheet was computed from velocities atained with 120 grains of T7-2f
