Don't think I've seen this phenomenon discussed before so thought it should get in print for reference here. For anyone thinking about typical pistol reflex dot sights for rifles.
I got out with the super short micro length action howa mini grendel with Holosun 507c 2 moa green dot sight mounted as far forward on an extended front 3 slot base and dialled in at 206 yards, 201 horizontal. I shot over bags and dot covers about half that 15" gong at 206 and I had already played with 1" squares at short distances in house to gauge size so already knew the dot was approximately 3.75 moa with that closer eye relief than you'd get at pistol hold distances.
My group size here with factory hornady black is about same size as when I had the leupold 6x36 mounted on it earlier in year although I'd take the scope further if needed. I think I'll stick to mpbr with this one and for deer size game that dot size is like a built in rangefinder, if the dot fits inside kill zone pull the trigger, if it covers or is bigger than the kill zone have to start thinking about focusing on the bottom of the dot and moving it up as needed. Didn't get a chance to put out more gongs or play with holds to see where my capabilities started to struggle but will one day. This holosun was just an easier option than mounting iron sights as where would you start on that? a gunsmith required, this option no smith needed, as I wanted a no magnification iron sight option in the safe.
