Is My Scope Slightly Tilted?

[Stu_24 1]

Hi Guys

 

After a bit of advice, was down the plinking range shooting at some hanging balls at about 60 yards.

 

The pellets arc went away from the vertical line on my scope as it rose and then came back in line as it fell and hit the target.

 

Seemed to be about 2-3 mill dots over to the right as its highest point in the arc.

 

Thanks

If your scope is tilted you will be able to see it when you look through them

 

and if its a 22 rifle its supposed to arc and as long as you hit the target whats the problem

Cheers for the reply BigMac.

 

It's a .177 but I was more confused about why the trajectory was on an angle, surely with no wind the pellet should rise and fall in line with the vertical lines of the scope?

It could just be that it needs a little pull over to the left still

 

put up a a4 sheet of paper and put a pellet in it then aim for the pellet hole if you dont put the pellet in the same hole then it needs tweaking ,

 

see where the next pellet go,s if its to the right then it needs pulling over to the left

 

Could be your canting your rifle to the right i had this problem with a kt97 and if the trigger is not to your liking a bit hard to squeeze you could be pulling the rifle to the right to

 

what rifle are you shooting by the way

 

and hitting a ball at 60 yrds is a good shot lol

i would shoot at different distances 10 20 30 40 yards ect .if you gun is on target then it is fine . I do wonder if some scopes are not so well made I have a scope that shoots a tiny bit to the right a 20 yards at all other ranges it shoots fine . I think it could be because of the adjustable objective lens when it is adjusted for different ranges it moves the point of impact . what you are seeing down your scope could be something to do with parallax error your head or the gun may move a little after the shot .

Mac seems to have answered this well enough.

 

The tilt thing becomes OCD after a while. I personally use a spirit level and set the rifle up on a flat surface and adjust the vertical crosshair to 'central' to my eye. It means that if it doesn't look vertical when shooting, Im not holding the rifle perfectly straight.

 

Set yourself up a 10, 20, 30 40 50 and 60 yard target. Take the shots, the pellets, when there is literally no wind [good luck now its getting into Autumn] and the shots 'should' strike, under and gradually go over the POI until you get to your zero, then begin to fall under again as the distance increases. If its not doing it at normal airgun ranges, I wouldn't worry.

 

In all honesty, 60 yards as a long f***ing way with an airgun and loads of things can take account for the pellet moving left and right.

Cheers guys

 

I think I'll get the levels on it and see what they reads.

 

I was thinking if I was slightly out then I could be canting the rifle to keep the rectitule vertical which would explain the trajectory being on an angle.

 

Cheers for the advice!

Some cracking replies already

 

Just to add to this lighter .177 pellets can become unstable at range (have a look at teds holdover youtube vids) and they can be very susceptible to wind drift. Light pellets fly fast and slow down fast.

I did originally think wind but surely if the pellet was being affected by wind it wouldn't have come back in line with the vertical line of the scope just before the POI?

Just because you hit the ball dose not mean you hit it where your poi was

 

Say you had set your zero out to 40 yrds and it was just slightly of center of the bull its in the bull but not in the center of the bull if you no what i mean increase this by another 20yards and it will still hit the target but not at poi increase it again by another 20yrds and you will miss it all together as poi will change the farther your target go,s

 

If its slightly off at 20yards it will be a few inches out at 60 that's what your mill dots are for (not having a go at you bud)

 

Shooting at them distances takes time and skill to achieve and to do it time and time again with out thinking

 

good on you for putting in the time at the range it would of been a different post if you had done this out in the field on live rabbits or such .

 

Do as REZ has say,d he no,s his stuff when it comes to target shooting and im sure he will help you no end if you get stuck

 

REZ im out of likes mate so you will have to do with a thumbs up for now .

Ditto to most, if it helps any, hang a heavily weighted string "indoors", as said, set the rifle up with a spirit level on a flat surface.(say 15 ft away) ish.

When you are satisfied the rifle is perfectly level, look through the scope and set the vertical cross hair dead inline with the weighted string.

Stu if your rifle is still level and the vertical cross hair matches the weighted string perfectly,- tighten things up gently.Then zero to your desire and any scope cant will be eliminated.

p.s

I use the Predator gun rest mount and a scope rail mounted/fixed spirit level.(from sports match)
