I changed to Ultra dots long ago, scope drove me nuts. Can't see deer when dim out with a long eye relief. I used opens for IHMSA in the 80's and 200 meters was easy as I had perfect vision.
Now I am near 84 and two gremlins swing on the end of my barrels. Years ago I took deer to about 120 yards off hand with my .44. Best group off hand was 3/4" at 100. Cast bullet of my own mold making and design, 330 gr.
