Boddington is a jerk, one of the many aptly desribed by Jack O'Connor eons ago as doing more hunting over a keyboard than if the field. He's strictly in it for the money . He's a rifleman, with no interest in shotguns whatsoever, but needs to keep subscribers pacified, one of the reasons I don't read the gunrags anymore.
If you asked him if he pattened that shotgun with the buckshot before the leopard incident, I'm sure he'd be stuttering, LOL.
With that being said, shotguns and buckshot account for a lot of deer, some at pretty phenominal distances(for buckshot). I live is a state where you can't hunt centerfire rifles for deer, only slugs or buckshot. Some guys here prefer buckshot, over slugs. I know a few who shoot 10 gauges, and are very comfortable shooting at 80 yards, and they drop deer at that range, bang flops. It goes without saying, that a LOT of work went into patterning their guns with various buckshot loads, and that is the key. If you don't pattern the gun, you have no clue as to what it can(or can't) do, kinda like buying a bore sighted rifle and just taking it out hunting, hoping for the best.
Buckshot penetrates light skinned game just fine, even at longer distances, you simply have to come up with the right buckshot/choke combination to deliver enough of the buckshot to the boiler room at the intended distance.
We personally use a 9 inch paper plate for our buckshot testing, because thats about the size of a deers boiler room. I don't care where the pellets go outside of the paper plate, I just want to know what I can deliver to the boiler room. Always pattern the gun, even a brand name within the same size buckshot can make a heck of a difference. Many will tell you a tight choke ruins a buckshot pattern, but it all depends on the individual gun/choke.
Recently, my son was patterning his Winchester 1300. He found that using his HS Strut extra full turkey choke at .665 constriction, he can consistently put 13 out of 16 pellets of #1 buck from a standard Remington high brass load into the 9 inch paper plate at 50 yards. While he hasn't tested it further out than that, I'm sure when he does it will work out to be a 75 yard deer gun. So much for the theory that tight chokes always ruin a buckshot pattern, LOL.
While I'm not a big fan of buckshot and much prefer slugs, I've played enough with it and seen enough deer killed with it to know if you pattern your gun and come up with the right combination, it's pretty deadly, and well beyond the '30 yard max' you hear most laymen describe who have no experience patterning it and prefer slugs so draw a conclusion that buckshot is only effective to that distance.
