All round best ammo in my rifles is Fiocchi Match M320 followed by Winchester Dynapoint and the T-22. As good as Fiocchi, but more expensive is Wolf Match Target. I didnt get as good a result with Wolf Match Extra. This is at 50 yards with my most accruate rifle, a surprisingly accurate old Glenfield model 60. I bought some Fioochi SM340 Biathlon ammo expecting good results based on my experience with the M320 stuff. Was a real dissapointment - shoots very dirtyand is not as accurate as M320. Even had some split cases. For me, the best balance of cost and performance is clearly Dynapoints. I have given up on Remington and Federal bulk ammo. The Remington is too dirty and the Federal is inconsistent with lots of weak rounds.
