I went with a Leupold fixed 6X on a .308 “ranch” bolt gun.
Reasoning as you- weight consideration.
Went with their Ballistic reticle which keys to my .308 load of 150 Accubonds.
It has endured a lot of abuse in the rack of the Ranger and has held up- no problems.
The rifles at the ranch, I’m not.
I may have photos- will post if I can find something.
Certainly less than 500 rds (predator control/general purpose Bolt gun).
It has seen a fair share of abuse, most as a loaner gun to some “non gun” buds.
The gun has maintained zero.
Rings/mounts are Talley.
Rifle is an 84M Kimber and was a purpose build. With the fixed 6X I felt no need to go 30mm tube. The entire concept was lightweight, “stalking rifle”.
Historically a fixed power scope is alleged to be more robust than a variable.
Weight with scope/rings is 6 3/4 lbs. Barrel was floated forward the lug, action bedded, 2.5# trigger.
Shoots 3/4 MOA with handload of 150 gr, Accubonds.
The scope/rifle has to be 15 yrs. old and still works as day one.
The op wants to save weight. The TA55 is a heavy weight at 25oz. Many LPVO are lighter than that. I love ACOGs but the 5x and 6x models do not make much sense.
