I have been shooting CCI SV in auto's since my first Marlin 99C at age 12. The boxes are noisy in your pocket while sneaking up on vermin, but always did the job. Do not shoot rim fire auto rifles any more. The S&W 41 likes them. So does the Mark II. Fun factor is high and cheap.

I am glad you ended up with a good tube.

Gun Shows are almost as comical as boat ramps in the Spring.
