I agree with a prior post... I consider .44 mag out to 100 yd. in a rifle only. It's not a 200 yd. load. It's going to be dropping off fast below center, velocity and energy beyond 100yd.
If you look at most ammo mfg. charts for .44 mag they don't even give ballistics beyond 100 yd.
It's a great caliber for pistol and pretty good in rifle within 100 yds. Just don't try to use it for something it wasn't designed for and you'll be fine with any scope/rings that hold center within 100 yds.
