I sighted in my Ta 55 scope today mounted on a .308 M1a with great results. First, for shooters with aging eyes like mine that need reading glasses, (I wear #175)The reticle pattern and target area are both crystal clear at all ranges without diopter adjustments or focusing anything.
It seemed the BDC reticle matched up nice with 168 grain ammo. I only tested out to the shooting ranges maximum of 300 yards, but at that range, bullet groups matched the Ta55 reticle predicted impact point.
Pros: Easy to set up and use. Very high quality. No batteries needed!
