I have tried one of their standard velocity offerings, it's not bad, but not sure if it's the same that is in the SG ad. In my old Marlin 25 at 50 yards it will keep a 5 shot group within 1.25 inches or so. For reference, the same rifle with Wolf target or Aguila Super Extra standard velocity will put 5 shots in 3/4 inch, with some groups smaller than a dime.
