Air Venturi Avenger barrel twist rates

.22 Using cleaning rod and a brush and again with a Jag and some patches. I marked my 32-in stainless steel one piece rod with a tape at the handle and then pushed it all the way in until I touch the bolt and when I marked it at that point and pulled it out I measured 20 in and a tape only turned halfway at the end so it looks like it's a one in 36 or somewhere about that. I guess they're just putting the minimal spin and letting the stabilization come from the standard pellet drag.

Now it's got me very curious and I will repeat this process with a Hatsan flash and Kral mega 22 as well as the Eagle claw.

Well I wasn't really sure that I did that so I did it again four or five times I think. So the Turkish guns flash and kral sure look like 22 inch for one revolution and the avenger has a 24 inch barrel minus a quarter inch or something like that and I only got a half turn so one full turn would be like 40 inch. The Seneca eagle claw is at 16 so my marking tape could actually turn more than one complete turn on that gun. I've got some round balls that I'll push down each barrel into a bucket of water with rags and I'll post the pictures of the land and groove marks for each of these four guns.
