Ive got a Leupold Mk4 3.5x10 LRT that I presume works great. Ive used it in the past to shoot out to 900m and now I use it to about 200m. Ive been reading alot recently and keep coming accross scope tracking and issues that Leupolds might have. Can someone please explain to me how I go about checking my scope's "tracking". Thank you.
