Grew up hunting a bow or shotgun only county, slugs not allowed. Always used Federal 3 1/2in 00. I believe they had 18 pellets in them. My dad and I had a pair of Mossberg 835s.

When I was 9, dad gave me an old single 20ga. Had a doe and yearling feeding on some crab apples. I pulled the trigger on the doe and both fell over. Must have been quite the spread. Pretty neat for you first kill though.
