Sig 3x12 mm - SIG SAUER Buckmasters 3-12x44mm Rifle Scope 1in Tube Second Focal Plane

I got 2 of these and a range finder at a smoking deal.
Know I know why on both mine .338 & my.270WSM it would not track well at all.
I have taken over 150 big game animals with these rifles. The .338 had a Leupold 3x9 for the last 20 years. The .270WSM a Burris 4.5x14.
I made 100 loads for each and was going to have to load up again, and my son talked me into a higher power scope for our North Montana long shots on huge deer 350+lbs. Never had to shoot more than 1 shot with either gun, had to finish a couple with my .22 pistol.
Shorten it up, their scopes failed miserably for me, glass was clear but hard recoil would not let the scope track worth a hoot.
