Charlie, I'm not real familiar with those large shot sizes but the one chart said that the recommended shot charge for the 8ga was 2 ounces. The other table lists Tatum shot as having 50 BB sized pellets per ounce so 2 ounces would be 100 pellets. I don't know if 00 buck is smaller or larger than BB. Size 2 shot would have 172 pellets in 2 ounces.
