scope running out of clicks

kellzar

got a new scope today and set about sighting it in at 50 yards first group were 8" low and 3" left. started adjusting the turrets when all of a sudden my up turret is out of clicks. this being ireland it started to lash rain so i headed home.
ive reset the scope to it optical center and hope to go at it again tomorrow.

If your scope is not mounted properly you will experience loss of clicks prematurely.

You should have feet of clicks @50 yards.

What make of scope, and what make of mounts?

zos 10-40x50. i used the ones that came with it they look fairly rubbish but since its on a 22 i thought theyd be ok.

Yes on a Burris and Hawke. The Burris was a piece of crap even though it was brand new, and the Hawke was on a .22 which i've found to be a PITA for using up clicks/MOA due to the subsonic nature of the ammo.

Which caliber rifle is it on?
Centralise the windage. So if its 200 clicks in total have it at 100. Then dial the elevation down to the bottom. As in no more clicks. Now count the clicks or MOA until the scope dials out at its top end of adjustment. See how many you have.

If we can get the caliber and amount of minutes or clicks then it will shine a light on the possible problems.

kellzar

its on a 22lr. it has 400clicks on both turrets ive set both at 200

Cass

You posted just before i did so i edited my last post respectively.

I had a Tasco on the .22 and changed it for a Hawke. It came with more minutes than the Tasco, but i only just got my zero. I took of the scope and mounts, shimmed the rings/base then remounted. Gained back 15 (60 clicks) minutes so all sorted.

kellzar

im thinking of shimming it but would like to avoid it if possible, would higher/lower mounts make a difference?
the mounts are 20mm high atm

Cass

What clearance of the barrel have you with the scope?

kellzar

at a guess id say 5-8mm

Cass

It could come down a little, and you'd gain back a small amount of adjustment, but nothing worth talking about. Is the scope in 1/4" clicks?

If it is then you have 100 minutes of adjustment, and i'd be very surprised that you cannot get a zero with that much. However if its 1/8 click value thats 50 minutes and entirely possible to run out of minutes/clicks when trying to get a zero.

kellzar

its 1/8 though on the turret it doesnt say yardage. but the generic manual said it was 1/8 for 50yards

Cass

1/8 at 50 yards would be 1/4 at 100 yards, but the fact that you have 1/8 clicks means you have 400 / 8 = 50moa of adjustment. On my hawke it used 51 of its 52/53 moa to get the zero.

I'd say thats your problem. The only solutions so are;

• Shim the rear ring
• Get a 20 moa picatinny rail
• MOA adjustable rings. These are higher on the back than front so bascally the same as shimming. Not too common (i think) and i've only seen one set before.

kellzar

the lad i bought it off said he never had any issues with clicks, so im going to have another crack at it tomorrow and see how it goes.
thanks for all your help

Cass

Is the scope and the rifle the same as the lad had or did you just buy the scope? Because it suited his rifle does not mean the same zero will apply to yours.

I had an old Tasco on the .22 before the Hawke. It only had 40 (ish) moa (160 clicks) i was able to zero the scope and still have enough clicks/moa to get me a 100 yard zero. When i put the Hawke on, even with 10 -12 or so more moa it just about got a 50 yard zero. Meaning there was at least 18 - 21 moa difference between the Tasco and Hawke scope using the same rings with the same objective lense eize. A few moa out i could understand but not the "huge" amount it was out.

kellzar

i just bought the scope. he said he had it on a few rifles and it was fine on them all. if tomorrow doesnt go well ill buy a picatinny rail and see if that will work

Cass

What model .22 as rail are hard to come across and inclined rails harder still.

clivej

What rifle is it on.
If its a Ruger 10/22 then your problem could be barrel droop.

Anyway to shim up the back mount cut up a beer can and fold over a few times to get the thickness you need, about 4-8 thick should get you there.

I had two of those zos scopes before had one on my .308 and one on my .22. Never had an issue mounting them as i bought new rings when i got the scopes and binned the ones that came with it.

kellzar

rifle is abaikal toz-17-01. tried shimming it today but no joy, gonna try a new set of mounts on it tomorrow see how that works

the mounts that come with that scope should be binned,they are said to be pure crap:eek: so get some sportmatch ones and see how you get on;)

I have a ZOS 10/40X60.
Sportmatch Fully Adjustable Mounts worked on my CZ and 10/22, got the high mounts fits fine and was able to zero in at the first line on the turret for 50mts, a heavy scope on a .22.

Very small field of view at close ranges, great for long distances.

G.G.H

I had the same problem with the same model scope, my problem was that the scope wasn't mounted properly and was sitting at an angle.

I *think* my Ruger 77 rings are like this. Pretty sure.

Mr.Flibble

For the small amount of trouble involved, it's worth trying swapping the rings around.
