Ran a test this past 3 mornings. I'd run up the canyon behind my house just at 1st light and shoot 100 yd groups.
I'd shoot a cold bore shot, then a 2nd and 3rd shot; three mornings in a row.
The wide shots at 11, 7 and 1 are the CB shots in that order. They run 3". The wide shot at 2, well thats probably me, a bad piece of brass (wish I had remembered to toss it) or baaaad JuJu. It opens up to 3-3/4". The top of the car was icy and slick and the Harris bipod was not solid.
All the shots in or touching the red are either 2nd or 3rd shots from 1st, 2nd and 3rd mornings. I called the 3rd shot on the 3rd day to the left at 8 touching the red. Other wise those 5 shots would have gone 3/4"
The interior of the red square is 3/4".
My question is this.
Do I accept the fact that my cold bore groups suck and refrain from shooting beyond 400 yds for elk(3" x 4 = 12" Group).
Or, I do I take a spotter shot and drill an elk out to say, hell, 1000+ with the 2nd shot.
And, would you move the zero 1/4" down and left?
