Man alive, not one single guy here grew up with a BB gun. That is truly amazing.
Anyone who ever owned a BB gun knows that they are .177 caliber. So BB is the shot size that is closest to .17 caliber. Cannot believe all the mistakes made here regarding the caliber of shot.
#4 Buckshot is going to be more traumatic than 00 Buck, for the person is going to be hit in far more places. The odds of being hit in vital locations thus goes way, way up.
If you use copper plated #4 buckshot, that is going to improve penetration. So make sure that the ammo you use is copper plated. They also tend to pattern better.
Any notion that choke has no effect on shotgun patterning is completely bogus and untrue. I have a light modified choke in my FN SLP. It is halfway between an improved cylinder and modified choke in its restriction.
Federal unfortunately discontinued their Premium 2 3/4 inch Buckshot load that used copper plate buckshot. However, they still produce it in a 3" inch version with 41 #4 Buckshot.
I still have over 100 rounds of the discontinued 2 3/4 inch load, which was loaded with 34 copper plated #4 Buckshot in it. And that is what is in my FN SLP currently:
My FN SLP holds 8 +1 of these shells. That is 9 x 34 = 306 Buckshot without reloading. That is a lot of holes.
