The method of shooting.
I shot 3 shots out of each rifle, one after another.
After each shot I alcohol swab each shot, 3 up, 3 down. Turn over the patch, 1 up 1 down. Working the crud ring when I got to it. Slowly. Then dry patch, 1 up 1 down. Then 1 patch of bore butter, down and up once.
After each shot I used a spotting scope to make sure of each shot where I hit. After the 3 shots I walked to the target and marked the shots.
I shot each target for only 1 type of bullet with both rifles.
For the penetration test. After each shot. I placed the soil displaced on the ground back into the bucket and packed it back down with a 10 lb tamper..
