Anyone here have one? I have a bunch of coopers that all shoot well. Looking for a light 600 yard shooter.

Yea I've got one in 257 Weatherby. I have a Swaro Z5 3.5-18x44 BT with the Outdoorsmans Turret. With a 300 yard zero it is good on the dial to 900ish I think but way out there. I just shoot Weatherby factory ammo in it. The 100 grain Triple Shocks work well on antelope and deer but I have gone to the 120 grain Nosler Partitions especially at longer ranges.
