My question is whether the break-barrel type of air rifle suffers any accuracy disadvantage when using a scope vs. the side lever cocking type. Does the barrel, after cocking, return to EXACTLY the same position so the scope zero does not change or does it become a little loose over time so accuracy would suffer? Without knowing, it would seem that the side lever cocking type of air rifles would have an accuracy advantage.
 
Fixed barreled air rifles will always have a slight advantage over break barrels but it will generally only appear over time and use, as high srung breakers have been known to bend their barrels slightly with a lot of use as well as the lock-up degrading.
 
Yup. But in the time it takes for the lockup to change/barrel to bend, you're certain to have changed ammo or conditions which would have required a rezero anyway.

A good quality airgun won't show any appreciable difference. As the price (and quality) decreases, I'd start to get concerned about this sort of issue.

Most high end, sporting/field air rifles are capable of regularly hitting a 200mg ibuprofen tablet at 25 feet. High end, side cocking target rifles are capable of 10 shot groups at 25 feet whose spread will be less than the width of the period at the end of this sentence.

What kind of accuracy are you looking for? For me there is no appreciable difference in the accuracy potential between the two types of air rifles.
 
I'd be putting it on a Diana/RWS model 45 that was purchased in 1989. I don't think it has had more than 50 pellets through it so it is still pretty tight for now. Most shooting would be for pests at ranges of around 50 ft max. I used to be good with the irons but anymore...................
 
You might try aperture sights. I've had very good luck with them on my springers.

If you buy a scope, get one specifically rated for airguns, and maybe solicit some advice on scope mounting from an airgun forum. The odd characteristics of spring-piston airgun recoil makes mounting scopes slightly more challenging than one might expect.

I don't think you'll ever notice any lockup problems with a Diana airgun. If there are changes, I would expect them to be very minor, and to take place over a very long time.
