I shot CCI standard velocity, Aguila extra and some Remington bulk ammo. I’ve reading that power rounds would stick. I just sent this back to SW, I guess I’ll see what they have to say.
I have a 686+, 2 Kimber K6 (2 and 4in) and finally got my 617-6 last week! Very excited! It shoots well, feels good in my hand; however, I have tap out the spent casings with a light hammer and a dowel. Severely deflated my expectation of a quality piece of hardware.
