So, just in time for hunting season I got a brand new Barska Euro 30 2.5-10x. Hooked it up with the included rings, and out into the backyard for some zeroing.
Got it zeroed with my 325gr FTX, and then I went to check the group. Lo, and behold but I was shooting all over the place. When I reached down to check my scope, I disovered that the recoil had sheared one of the screws on the scope rings!
Suffice to say, I went out and bought some warne rings, and now I'm shooting .75in at 100 yards, just in time for dear season.
Moral of the story, free scope mounts suck.
