I guess I wasn't very clear in my post, all I was doing was breaking in the barrel cleaning after every shot, letting the gun cool down as I had six other rifles to shoot and the temp was 40 deg.
Every shot was made at the same aiming point on the same target so as not to waste targets, I was not trying to make a bragging group so I could come here and gloat.
Bud, I think most of us knew that...
We just like to obsess over tiny nuances. Not just rifle groups...just about anything will do
