Stick with it. Consistancy in everything like grip, shouldering and mainly head position should bring back memories.
I'll be 67yo next year and I still enjoy long range varminting, even though there's not much walking involved these days for me. I love target shooting as well and I'll give up if I can't hit an Orange at 500 metres, a Golf Ball is still very much the target aim size.
My top rifle I have a March Tactical 8-80x56mm and I can tell you that anyone not used to high power scopes has a battle to get an image when they first line it up and typically complain that all they can see is a black reticle... experience is all that is needed, I can sit behind that scope with my eyes closed then open them and a perfect image every time... it's practise keeping your shooting position constant in my view.
Shooting with that power scope I sometime tend to get a little distracted when I see tiny little 2mm black ants or a tiny fly crawling on the target, just can't help putting them out of their mysery and off my target.
at 2-300 metres that is, 500m for an ant is pushing the friendship I have with my rifle....
