Where the dot is in that picture is the where my bullets impact at 25 yards, so yes that lollipop picture is the picture I use. Although, my front and rear sight are completely out of focus with shooting a red dot because it allows me to just concentrate on the target. I've shot with the dot on each corner of the window at 50 meters at KH Silouhette and was still hitting steel without the dot centered in the window.
When I shoot on my coworkers ranch at 7 to 15 yards my bullets will impact maybe about 2" lower on paper when covering a bullseye with the red dot. Makes sense because when I had standard height sights on that gun and no red dot, I would impact almost 4" high when attempting to cut the bullseye in half with the front sight at 25 yards.
“Where the dot is in that picture is the where my bullets impact at 25 yards, so yes that lollipop picture is the picture I use.” I was more refering to that your sight picture was the lollipop dot in the front sight blade. I was always told/taught to try to keep the dot centered in the view window, be it for handgun or long gun. Yeah, under stress, you may not have time to do so, but one should train for that sight picture for reps and muscle memory. I just never considered the way you described.
I had assumed that quality dots all have parallax correction. So if you zeroed properly, the POI will coincide with your POA. Yeah, you will be closer if your sight picture when you break the shot is what it is when your zeroed. When shooting with the dot, I also don’t really see the irons. When zeroing, I’m shooting at a slow and deliberate pace and I might notice the irons, but not when shooting at less deliberate pace.
I’ll have a chance to shoot with the dot in a training environment soon, so will see.
