There are two problems I'm having. First is I can't get the same brand ammo twice in a row (everybody's out here) and second is the gun kicks like a mule so it's hard to shoot too many shots at once.
I shot a fair group with Remington ammo at 9x, but it was off 9" to the right. Zeroed it & did well. When I went back, the scope was at 4x and I had Nitrex ammo (I know - two variables). I put it back to 9x and was still about 6" off to the left with the Nitrex. I'd like some consistency. I wouldn't think ammo would throw it off that far??
