Origin and Cayden barrel twist rate

[TheCarFather]

Do any of you know the barrel twist rate on these rifles? Benjamin Cayden in 22 caliber, and Umarex Origin in 25 caliber. I tried searching and couldn't find the info.

Reason I'm looking for it is for the Strelock pro app.

Take a bore brush that has a rotating handle and insert it all the way down the bore with a patch. add a small flag made from a piece of tape. right in front of the muzzle. Flag should be in the 12 O'clock position.

Slowly pull the handle until the flag spins around one complete revolution and then stop.

Measure the distance from the flag to the muzzle and you have the twist rate.

Very neat trick! Unfortunately I don't have a cleaning rod, I just use a crown saver for cleaning with patches.

Let me check my Cayden....

1/17 is the Twist rate I'm getting. I goggled and found Benjamin Marauders have a 1/18. Hope that helps
I checked mine twice 17" for a full rotation.
