Is my scope toast? Added pics

[igojuone]

At the range yesterday trying to figure out why I can get a group. Three down the range at 100 yards and second and third shots progressively move inch higher and 2 ½ inches to the right so first and third shot end up 5 inches left to right spread and 2 inches higher. I took scope off and put three shots in a 3 ½ x 2 inch group with iron sights.
Does this indicate a bad scope and if so any idea the cost of a typical scope repair?

Need moar details.

What kind of scope? What caliber you shooting? Do you have iron sights?

Sounds like your scope is toast, but it's hard to say what to do about it without more details. Fix, repair, warranty might all be options.

It's an older Tasco Titan, 3x9x42 with 30mm tube, made in Japan(when Tasco made a great scope) and has been tough as nails, been through a lot.

Yes iron sights, that's how I got the second group, not the best group but one shot with glasses off(see the sights but target blurry) and two shots with glasses on(see target but sights blurry).

Three rounds is not a very good indicator.
As one flinch can give the appearance of not grouping.
Also, are your rings torqued to the rifle properly? How about to the scope properly?

 

[igojuone]

Yeah everything is torqued and this wasn't first trip to the range trying to figure this out, I've shot every good groups with same rifle and same ammo in the past. Other "groups" have started here and ended up 5 or 6 inches to the right or high or low. I won't claim to be a sniper but if I can somewhat group 3 with poor eyesight and iron sights I should be capable of better with the scope.

I agree - results are inconclusive. One possibility is that the scope is "walking" - as many do after a turret adjustment. In this case, the scope settles down after a few shots. I've has this happen with some pretty decent scopes, particularly in cold weather.

 

[igojuone]

How many shots needed before the "walking" stops?

Just out of curiosity did you check your mounts? sometimes one of the bases loosens with time.

 

[chappy]

i would go with dead scope. your open site grouping is fine. mount a known scope and try again. if the rifle groups your scope is done.

If it is the scope, maybe Trace optic repair in Calgary can fix it. Having said this, I recently had the groupings on a rifle turn to chit and turned out my bases had loosened.

 

[Suther]

Sounds like you should take it all apart, and put it back together. That way you know nothing is loose. If the scope still can't be zero'd its the scope thats the problem.

Switching to another scope might make you think its the scope, when in fact it may have been the rings.

 

[igojuone]

Yeah thanks everyone, I'll start from scratch and try again then try a different scope before sending anything away or buying another.
