Thanks for reaching out Harold! This shell is loaded with #4 birdshot (0.13" pellets), not #4 buck (0.24" pellets). We haven't got any #4 buck 12ga ammo in store right now, but we have got three boxes of #1 buck loads in stock as I type this: luckygunner.com/12-gauge-2-3-4-super-x-1-buck-winchester-5-rounds
We also have #0 buck by Aguila in stock if you don't mind going a little bigger: luckygunner.com/12-gauge-2-3-4-1-3-8oz-0-buckshot-aguila-25-rounds
