Rate of twist

[oldnamvet]

Do any of the manufacturers state what the rate of twist of the rifling in their barrels happens to be?

Most LW barrels are 1 turn in 450mm (17.7").... Airguns typically seem to run between 16-18".... The .25 cal MRod is 15.5"....

OK Thanks.  that is about what the .22LR standard is -- 1/16.

I know that most of the Crosman barrels are 1 in 16, and I think that most of the Powerline barrels from Daisy are as well.   The Daisy Avanti barrels I think are something like 1 in 15 or there abouts.

As I understand the majarity of AirGun barrels are 1 in 16, it seems to be some kind of standard.  There is not the verity that you have in Firearms.
