    I shoot Aguila SSS 60 grain subsonic ammo out of my 10/22 with a 1:9 twist barrel and it is just fine. But using a slower twist pistol or rifle will cause keyholing and will damage a suppressor if I use it. I was wanting to use this ammo in a suppressed pistol. Anyone know what the twist rates of a Ruger 45/22 is? Or a Walther .22LR pistol?

    Is there a very fast twist-rate pistol or barrel out there for my purposes?

    Ruger 22/45, Mark II standard barrel is 1:14 and bull barrel is 1:16. Ruger Mark II Competition is 1:15.

    It also is not 100% reliable. I have had several misfires in my SSS ammo which has stayed in my safe for five years now. I also fails to function my 10/22.
