No distortion so far, don't really expect anything with components listed. At 25 yards the chicken can do one 360 but the rest just swing a little. I didn't do too much experimenting to stop the chicken, I actually kinda liked it. It would be easy to install a stop at any predetermined angle if preferred.
The one thing I did not state with original picture is the legs come off quickly for compact storage in the trunk or for shipping.
I think one set will be at the next Selkirk .22 rimfire silhouette competition for display according to the owner.
