My original concern has been answered and i though brilliant, but something i overlooked was how thin it becomes on 12x.
For that reason its going to be too thin. I dont shoot on a given mag. Every target i shoot on a different mag if i feel the need to.
The downside is working out the windage hold off as i work it out off the 40mm kill same as those who have a target dot.
Let your shooting do the talking.
It's not the aim and release that decided the shot, it's the preparations.
