I used either the 2 3/4x Redfield or the 4x Redfield widefield scopes for years and they worked plenty well enough. harder for me to find fixed power today other than what I already have so I have wondered into variable power. Started with 3-9x's and found them normally on the lowest power. I've never shot at a big game animal at over 3x!. My favorite today is still fixed power scopes and picked up a used Weaver K4 several years ago but have found my favorite variable's to be 2-7x. Smaller and lighter than other scopes that have power's on them I never use. With the 2-7 and 3-9's I use 6x for sighting in and load developement. Makes shooting at a small target easier. For my fixed power scopes I make my own targets so I use larger aiming points with them. Also my aining points are diamond's and the corner's are good for lining up the crosswires.
Forgot to mention, my lasr elk rifle, don't hunt them anymore, is that old 2 3/4x Denver Redfield I got back in the early 1970's for my elk rifle then, 338 Win Mag!
