sample of 1.
I don't normally use factory ammo but, as you say, I picked up 5 boxes of corelockt ultra 160 gr. 7mag ammo for $24.95 a box.
They grouped very well sighting in so I took them elk hunting.
1 shot @375 yds tight behind the front leg.
Blew through the cow - she moved all of 20 paces after the shot.
Like I said, sample of 1, performance was excellent, it was the price that was suprising.
