No, I have not fired the SK ammunition.
I’ve been buying it for a while from MidSouth Shooters.
Don’t think they load subsonic, but I like the accuracy I’ve seen with SK ammo. I like full 40 grain loads.
I have some sub sonic Aquila 22 ammo. Also have some of their target ammo, bought it when nothing else was available. It has it’s own odor. smile. Does not burn clean.
I’m not impressed with most high velocity but light bullet mass 22 ammo.
