Alright, I have to be doing something dumb, and need some help.
I recently picked up a Ruger American Rimfire in .22 LR with a 22" barrel. I've been very pleased with it so far.
I ended up adding Tech Sights, which I've used for 10/22's in the past and have had great experience with. I went to the indoor range a few weeks ago to do some initial testing of the sights at 10 yards (as far as my range goes), and got everything on paper. I had to bring the elevation down as far as it would go to get it about to print POI about half inch higher than POA at 10 yards.
I went to try to zero it this afternoon at the outdoor range, and found myself shooting about 5 inches high at both 25 and 50 yards. At 100 yards, point of impact is about 2 inches higher than point of aim (as far as my eyes can tell, anyway, holding 6 o'clock on a 4 inch black circle).This, of course, is with the rear sight elevation set as far down as it will go, and the front sight is not height adjustable with the RAR Tech Sights like they are on the 10/22.
It feels like I am missing something obvious. I have a hard time believing there is anything wrong with the sights or the rifle. I'm trying to visualize bullet trajectory. Is it possible that by "zeroing" the rifle at 10 yards I've screwed up the bullet trajectory such that I now need to counter-intuitively raise the rear sight to lower POI? Is that a thing?
Grouping is overall acceptable, and I'm really enjoying the rifle. Worst case, I guess I can dump iron sights and move to a mounted optic, but I am pretty determined to make iron sights work on this bad by.
What am I missing?
EDIT TO ADD: For ammo, I was testing with both Mini Mag Varmint and Federal Auto Match.
