Red Dot lost zero.

[lunghit]

So may 1st I shot my opening day bird and while cleaning it I noticed a decent amount of TSS in the breast. I took a practice shot at 40 and my POI was a good 6" lower than it should have been. Without shooting the gun is there a way to test the red dot (FF3) to see if there is something wrong with it? Same ammo and never dropped or bumped the gun.

I am actually thinking of seeing if the gun will shoot POA/POI with just the bead. I hate not having confidence in my equipment. Thanks in advance.

A laser bore sight will give you a pretty good idea.  I use a bore sight to align the dots, then I dial it in with a target.  This year I almost didn't check zero on my 3 turkey guns.  Glad I did because my son's gun was way off.  Now I'm convinced that I need to check zero on each gun before each season.

I use a bore sight also but it isn't perfect.  An unusual way I have zeroed my sight is to replace the turkey choke with an improved cylinder choke and then bench rest a few foster style deer slugs at 25 yards. It really tells the tale.  For some reason elevation is always the problem if there is one.

I guess I'm lucky in that with all my red dots on my shotguns, low brass target loads hit the same place as my TSS loads.  So a quick and cheap shot with target loads before season is all it takes.

Just curious what do you think changed the POI on your son's gun?

I'll have to pick up a bore sight. And yes I now learned to test shoot every year but I'm just glad the bird was not wounded and lost.

That's a mystery.  It was dead on last year.  He hunts without me most of the time so he could have dropped it or banged it on something. If I do that the first thing I think of is checking zero.

Ok thanks for the reply. My main concern is the red dot moved from the 3" 20 gauge recoil. I know for a fact that it was not dropped or bumped. I would have definitely checked the zero if that happened.

My swampfox was off left and low on my 20. On my 12 my nikon was 4 inches right. Everything was tight. I think they get jostled going up and down hill and dale. 1st time my nikon has ever been off. It pays no matter what a pain it Is to check zero. with the 20 i cut the bottom of dots out at 8 yards with birdshot and im usually pretty much on at 40 yards with tss 1 or 2 shots. Best to all.

2019 I had to return a FF3 that stopped holding zero. Burris confirmed the failure and replaced it no questions asked. Rare but it happens to all sights.

The one thing I did notice is when I have my gun on my ATV gun rack it vibrates a lot. The vibration along with the bumps from normal dirt road driving might have done it.

I sent an email to Burris and I hope they ask me to send it in for inspection. Thanks

Yeah, a lunghit is good for deer but not ideal for turkeys...best of luck.

Just a thought. But once you have it dead on with tss. Why not shoot a cheap birds hot load and keep the target for reference? If you need to verify, shoot a birdahot load and compare to the target you saved.

X2 or a cheap lead turkey shell like longbeards. As long as the velocities are close then you are good.
