Re: 22/45 upgrades...
I got it zeroed the other day. I was zeroing at 10 yds until I get the feel of it, I will then will probably zero at 50yds with it (I use it to plug ground squirrels). Was having problems with the elevation turret. I would adjust and it wouldnt move. It was shooting about 5" high @10 yds. Went back out one morning, adjusted it after 3 shots and it zeroed right out.
I know the height is bad, but I can still use the irons if necessary, and surprisingly it lines right up with my eye when I throw it up.
