Are supplementary aiming points allowed on All American benchrest targets? I have scoured the rule book and not found a distinct answer.

Aim at a point to your liking, sights adjusted point of bullets impact center on the record target. Example bullseye service pistol holding bottom of the bull, bullet strike center.

It’s a common technique can’t say if it’s legal ASSRA.

Can’t see any advantage to holding point pictured in a number scored match. Group size scored target it might have possibilities

Thank you.

I can see where it could theoretically be an aid in defeating mirage on a hot sunny day when the target image starts "floating". But, how would one quantify that so that shots aimed at the bud land in the center of the bullseye?

Also, perhaps, an alternative aiming point can obviate the need for sighting elevation adjustment with the bud placed low or high depending on distance to target versus distance at which one is sighted in for. 

Solutions, I fear, which are based on many deleterious variables....

Why add the green dot to aim at as a supplementary point of aim.

I use the top or bottom edge of the outer red ring on the target as the supplementary sighting point.

I can see using the larger dot if you have a 1 MOA dot in your crosshairs.

Do not need that large an aiming point if you get a scope with fine crosshairs and a 1/10 MOA dot.
Burris custom built my scope to have a finer crosshair and a 1/10 MOA dot.

How about an entire target frame as a supplemental point of aim. One year at Tommy’s range during an iron sight match Ron Smith used the target frame to the left of his record targets to use black targets (non ISSA I guess) to sight on and having the bullets impact the record targets on the adjacent frame.

As another test this morning, I shot this group with my point of aim being 6 o’clock on the white 25 ring. It worked out very well for me in bright morning sunlight directly on the target. An hour later, in lesser sun, that point of aim  was useless as it blurred in just a couple seconds. Just trying to do the best I can with changing vision.
