I stick to 00 because.That is my choice for inside the house.
If I had to move to outside…Federal Flite-Control 00 or #1, or Truball slugs.
FYI 0000B is not the same as #4 Buckshot.I stick to 00 because.
A: Finding 0000 around here is like finding chicken lips.
B: It's a longer walk down the hall than from the front door to the wood line, and the back door is closer. 
Is there a such thing as 0000? I know there’s triple-aught—000, but I’ve never heard of quad-aught.FYI 0000B is not the same as #4 Buckshot.
There is. it's .380 ( 8 pellets/3"). Developed for a farmer I think in Texas for pig killing.Is there a such thing as 0000? I know there’s triple-aught—000, but I’ve never heard of quad-aught.
That’d be…a .38? .40? Pellet (000 is .36, 00 is .32, iirc…); maybe a 6 pellet load in a 2.75”?
Sorry trying to do three things at once. multi-tasking is not one of my strong suits.FYI 0000B is not the same as #4 Buckshot.
