Any recommendations on particular 00 shells?
8 or 9 pellet 00 buck in reduced recoil. 1100-1200 FPS. Federal Flight Control would be my go to recommendation and what I keep in my guns. I shoot a lot of the Fiocchi reduced recoil LE 00 buck as well. I have not tried the Remington managed recoil but plan to pick some up at the local shop to test drive.
The reduced recoil stuff might not cycle a semi auto but works great in 870s and 500s.
