I'll get to know the Mountain Rifle as soon as our Weather breaks and spring gets here, 100yds will be my Max distance as I'm hoping I'll be within that when a Deer comes along, I usually am. I'm only going to take one deer with it in honor of My Father in Law then it's back to My Accura 1st Generation is my go to "My Baby" Mler she's all I use. I've taken several Deer out to 177yds with her using 100gr's of Pyrodox Pellets and a 240gr XTP Mag. That Mler is so accurate and dead on that last season I took 3 Deer with neck shots and all were over 100yds. Why the neck, because I hunt where's there's steep riveins and unwalkable bottoms where the creeks run through so if you get a shot at a deer at the top you better pray it doesn't go over the side. Most of them bed near the top in case danger comes then they run down, so if you don't drop em in their tracks your in for a long long drag up the side if you take a heart or lung shot.
