Hi all,

Question: I recently put an decent red dot (Ade Advance Optic) on my .22 Victory. I zero'd it at 10 yards and I shot bulls eye majority of the time (about 70 rounds of out 80). I then moved the target back to about 20 yards without adjusting the red dot and all of my shots sprayed VERY high, at least 4-5 inches from the bulls eye. I was completely confused as to why there was such a huge disparity from 10 to a 20 yard distance. Do I have to adjust the my red dot EVERY SINGLE time I change yardage? If that's the case, I'd rather not use it and just use my stock optics instead. I'm not sure what's going on here. Please help. Thanks.

Try about 10 different 22lr brands and speeds.

22cal pistols and rifles are picky as to which ammo performs best in that particular gun.

At 10 yards the trajectory of the rounds could still be climbing

Worse case is that your barrel is at the far end of acceptable tolerance.

Volquartsen makes aftermarket barrels that you should look into

Stakeout nailed it.
Bullets climb before they start dropping.
For this reason, I have several MatchDot II red dots.
They have a click stopped elevation knob.
With most loads, I click down 4 to 10 clicks when going from 10 to 25 yards.

Thanks for the info. I'll check out the new barrels. Question for you. Is this your pistol? I'm asking because I have my optic closer to the rear of my gun, whereas this one is in the front of the pistol. Does placement make a difference? Thanks.

i wish I had the clicks on mine. I have to use a screw driver to turn it a few notches. But it's not THAT bad. I'll take a variation of ammo tomorrow to try out and see what happens. Thank you.

Red dot sights have parallax, which you exaggerate by sighting in at a close distance. The reason for this is that the sight sits higher above the bore axis than iron sights. Imagine for once that your red dot is a foot higher than your barrel, and you're sighted in at 100 yards. Now try shooting at a target 3 yards away. You can see how it's going to shoot a foot low. If you try to sight it in at 3 yards, you'll be aiming way up in the air and shoot several feet high at 20 yards. Varying elevation is a fact of life with red dots, but you can minimize it by sighting in farther out. Try sighting in at 25 yards from a bench rest. Now when you move in to 10 yards, you'll be shooting a little low, but no where near as far off as if you sight in at 10 then move to 25. Curious how high the center of your optic is vs the bore? The higher it is, the more parallax you'll get.
