Good scope with sufficient magnification.
Sometimes, matching a target to the distance, magnification, reticle design and subtention can improve quality of aim and cut group size considerably.
I've made loads of custom targets to match a unique combination... from old Colt 4X AR scopes, to 2 MOA red dots, to German #1 posts to 60X 1/8" dots.
Have fun with it, and don't wear out the barrel too fast.
