Rio Royal Buck 12 Gauge shells (brand part no. RB121225) give shooters a proven buckshot option for home defense or hunting where a dense, effective pattern matters. Rio Ammunition loads this shell with #1 buckshot, a size that strikes a balance between pellet count and per-pellet energy, on a standard 2.75 inch hull. It is a dependable choice for shooters who want more pellets on target than a coarser 00 buck load while still carrying real stopping power. The 25-round box is a practical size, with 10 boxes available to a case for shooters who want to stock up.
