I was peasantly surprised this morning after zeroing my TRG42 from 100m to 400m. I dialed up and was 6in low. Made another adjustment and got it in the black shoot-n-see target. Once I saw the yellow dot in the black, I put an additional 3 downrange. When I got to the target I was pretty stoked to say the least. All I had was a cig butt to hold up to it for the picture - but you get the idea. later measured at 2.8cm
