When shooting irons, if I try and front sight focus I get double sights.
3 dot sights are especially problematic. I see a bunch of different dots.
It’s my non-dominant eye bringing in information and goes away when I squint the left eye.
I thought it was going to be a mess when I shot a match with irons…
But it never happened.
Turns out that I primarily shoot irons target focused or intermediate focused. The harder I target focus, the clearer my irons become (when both eyes wide open).
It’s how I learned to shoot (target focused dot) and irons were always really hard for me to get along with when I tried adding in front sight hard focus.
I don’t know if it’s the way I’m wired or because I spend so much time with dots. But I have a very hard time converging with front sight focus… but have had luck with target focused irons.
I know @Clusterfrack target focuses irons and I think the commonality is that you need a pretty good mechanical index to be able to do it effectively.
