Yes Steve, unfortunately, zero shift to a lesser or greater degree after moving the AO (or zoom) is very common on all but the most expensive scopes.

It's quite easy to test.....just set-out targets at a measured distances of say 10, 20, 30 40, 50 yards etc, and set the AO for each known range and then shoot a group. You may be surprised at just how much zero shift (L and R) you get. Obviously you get a vertical (up/down) change for each distance, but that's just the trajectory of the pellet, and is perfectly normal.

Side to side shift isn't normal though....and if you find a distance where the shift is excessive, try moving the AO back to the setting it was on when you originally zeroed the scope....and you'll probably find the windage (side to side) deviation disappears.

If it does, that will prove the scope is zero shifting when moving the AO ring.

Exactly the same test, but instead this time moving the zoom ring, can be used to show if a scope is zero shifting when the mag settings are altered. I would advise doing only one or the other at a time though, as moving both AO and zoom during the same test/experiment will only confuse things.

However, I once had a scope that would lose zero when moved away from it's zero magnification, but which wouldn't return to zero even if the zoom was then returned too. It drove me nuts having to re-zero that scope all the time, until I realised what was happening, so I set the zoom on 6x, rezeroed, and NEVER moved the mag ring ever again. Guess what.....from then on it held it's zero. ::)

It's for the above reasons I no longer move the AO or zoom away the settings they were on when I zeroed the scope. Ever.



I've only got one scope which retains PERFECT zero no matter how much I move the AO or zoom rings away from it's original settings, and that's a battered old Tasco 3-9x50AG that I bought second hand. Now that scope is a keeper, even though it looks as rough as a badger's arse. ;D

Thanks for that Gambo, Seagate and rabbit sniper.

So after reading what you've put, the plan was to go to the range this afternoon and start the re zeroing, and then look at the zero shift.  As well as setting up juniors gun, but as it hasn't arrived we aren't. I would say I shall go tomorrow morning. But as it's one of my towns beer festival, I shall be unfit to drive tomorrow morning ;) ;)

So hopefully on Monday or Tuesday we both will be hitting the range. I'll post pictures of juniors gun once he's got it.

So I went to the range today. After what I've been told by all the helpful people on here, I set the AO ring on my sight to 30yards and started to zero.

Well what a difference that made, I also think I've found the pellet my gun likes without doing a comparison ! Bisley Long range Gold.

So this is my grouping at 30 yards. Yes there's a flyer on each but I'm much happier now, the group is tightening up.

So I then tried to work out the hold under for 20 yards.

I then thought have a go at 35 yards

So yes I'm now getting there. I also mentioned to the shop guy that my goupings were better now I had stopped messing with the AO, he said that it shouldnt make any difference. Well as far as I can see, it does!

So all in all I'm one happy chappie, I can still get more consistent but I'm getting there.

Well done, Stevie. Making progress.

Unfortunately a couple of your pic links resulted in errors for me.

On of the 30 yards pics was OK and showed a really good group!
..........so I packed up and went to the pub.

Good read this thread, I'm sat at home with a knackered back so reading about you guys getting into the sport and learning the pitfalls of faffing around with AO and mag has reminded me of the palava I had doing the same thing, as actually put a tiny score on my objective bell where I want my AO ring sat so if it ever moves it's very easily reset.

Couple of weeks ago I was out shooting my .223, having very similiar arguements with my scope but then realised that the 500yrd zero I had dialled in wasn't exactly conducive to shooting 150yrd targets, it's horses for courses really, I now use an app called iStrelok which I believe can be used for airguns as well. It will show hold over/under and tell you how many clicks to adjust the scope.

Another fun excercise for your scope is to get comfortable shooting at say 30yrds, then fire one pellet, move the scope up 12clicks, fire one, move the scope right 12 clicks and fire one, down 12 clicks and fire, left 12 clicks and fire. What you should have is a box with a second shot next to the first one, fun challenge and test of your scope and shooting.

Hello Planet,

Firstly sincere apologies for not being on here for a long time. Life has a habit of getting in the way I guess. Winter and rugby (I still play (52) and I coach) so shooting time is difficult to get in the dark months.

So what has been happening to my journey since I was last on here. I now know my gun likes RWS super field. I've fitted an adjustable Butt plate to my gun, with I think is making a massive difference to my shooting.
Last weekend we both went to the Northern Shooting show. Cracking day out, Junior got to shoot the BSA ultra junior, which shock, horror. He liked, que can I have one of those please dad! He must think I'm made of money. He also had a go on the weihrauch HW44 pistol, which he wasn't so keen on (thankfully) I got to shoot the BSA R10, not that impressed if I'm honest, but very impressed with both the AAs510 and HW100k.

So we're both back on the range this Sunday and we'll see where our journey takes us.
