You are right. I was adjusting my scope as I went. Never more than four clicks at a time but I adjusted here and there. I shot left target to right. I shot the same sequence on each target. 4:30( bottom right) loaded 5 rds., 7:30( bottom left) load 5, 10:30( upper left) load 5, 1:30(upper right) load 5, center. Then I would switch targets and repeat.
Also, between the second target and third I took off my scope to shoot irons and to see if it would return to zero. I am pretty satisfied with the QD pepr mount but I did make minor adjustments after clamping it back on.
I finished up slightly high at 50 yards which is where I want to be for coyote hunting. I'm sure long range shooters cringe when they hear I take scope on and off. I'd like to be able to QD my scope and a decent red dot and feel comfortable that they'll be close enough to do the job when reattached. Wishful thinking?
