Tuning RWS Diana Target Problems

Have you checked the stock screws? They can come loose and effect accuracy.

Also, as mentioned already, it may be the scope. 

Good luck and fun shooting!

Thank you RacineJohn! Yes, I have done everything and just can't get used to the special holds and all the other requirements for accurate and consistent shooting with 'springers"

I have given up and gone to PCP's.
