I brought one of these home a 14" Contender barrel.It was a 6mm tcu rechambered and the guy knew nothing about the chamber job.I got it real cheap thought I could rechamber if it was a bad one.This is a great round very accurate,mild recoil.I'm not changing anything.

I have a similar round ona BF pistol a 6mm Donaldson wasp and have it in my Encore as well. A lot of fun.
