anyone tried the lothar walther barrel on a crosman co2 pistol?

For a 10 shot string that is indeed not too shabby, but have you tried measuring the velocity over the entire fill...?

Yep. It stays in that range to shot 23. Only peters off after that. Granted it has had a valve job, so while I don't get many shots, the consistency is good.
