3" vs. 2.75" buckshot

[Sharkbite]

At residential hallway distances none of the pattern enhancing developments in buckshot ammunition, at least since the introduction of the pin-fire breech loader of the mid-19th century, make any meaningful difference.

In fact, some of the newest “tactical buckshot” is detrimental at hallway distances. You get zero benefit of any spread

With the cheapest low tech buckshot available, 5 yard "hallway" patterns will really open up - to 3 or 4 inches!

At close range, a shotgun is a devastating and useful defensive weapon. And I base my set-ups, ammo, and tactics on this thought train.
I don't hunt with buckshot, it's solely intended to be used on 2 legged intruders( and I hope I never have to use it for that)!

So you looked something up. What’s your point?

Are you implying that OOO is the same as OO, with one less pellet?

Where’s the Wiki for that?

You left out an important word in my earlier reply: Measured.

As for industry standards, these are voluntary standards set by the Sporting Arms and Ammunition Manufacturers' Institute (SAAMI).
