Twist Rate for a Benjamin Marauder?

[X27]

I an looking for the twist rate for a .25 cal Benjamin Armada which I would assume uses the same .25 cal marauder barrel.

Also if you know the rest or the Benjamin twist rates that would be helpful too
.22 M-Rod
.357 bulldog
.22 Prod

iv looked some of them up but I just want to dubble check.
Thanks

The Armada is a Marauder with a different stock. All of the internal parts are interchangeable.

.25 Marauder barrel is 1:18 iirc. Can't check myinfo right now.

Twist rate is easy to check on any rifled gun using a cleaning rod and a tight fitting patch. Lube the patch with oil or gun cleaner and run it into the barrel so that it takes the rifling and turns with it almost to the other end of the barrel. Mark the top of the rod with a dot at the end of the barrel or a measured distance from it. Pull the rod out allowing it to turn following the rifling until it makes one full turn and measure the distance the dot moved out. Repeat several times to confirm.
