I have been doing quite a bit of reading on defensive shots for shotguns and it seems that the majority of sources recommend 00Buck, with #1 or #4Buck coming in 2nd and 3rd.
Now i am only talking about 2 3/4" shells. What i cant figure out is why would one pick an 8 pellet 00Buck over a 9 or 12 pellet 00Buck. And in the same line of thinking why would one pick a 2 3/4" 8 pellet 00Buck over a 2 3/4" 8 pellet 000Buck? Is it basically just a recoil issue? I mean all else being equal would it not be better to have 8 pellets of 000Buck over 00Buck? And within 00Buck line why not have 12 or 9
