Weigh 'em gunner. The powder doesn't take much room at all.
Now, are you calling BS, or are you honestly curious?
No BS, I cant figure why the 2 3/4 length shell packs more of a punch than a 3" magnum, and why, if they have the room, dont they add more of a payload to the 3" mag hulls.
Winchester part# X12C1B, old Bud said there is no equal in 2 3/4" 12 ga for entry/self defense loads.
