My results were mostly positive. The standard velocity stuff shoots pretty good in most of my guns. The exception being two Savage rimfires. In a GL it would do roughly 3 inches at 50 yards. Changed to CCI mini mags and same rifle would go under 1 inch. It also would not function well in a left hand Savage semi auto.
The big surprises were in a 10-22 and a Ruger Mark III. In both it functions 100% and is pretty accurate as well.
I have a case of the target stuff but never played around with it yet.
