Sure they have.I don't recall anyone saying that buckshot isn't suitable for deer, only that it's a short range proposition.
OK, please provide the exact quote and post number.
It's coming out of a shotgun, last I checked, shotguns were limited range tools. 50-60yds is the max effective range in most instances with anything but a slug. Although it will kill at further ranges.
I, no lie, killed a wood duck stone dead at 80 yds with heavi-shot one day. One pellet straight through the melon
Goes back to know your gun, your patterns and your limitations. It's a game of chance with a shotgun. The closer you are the better your odds but you aren't killing dinner if you aren't slapping that trigger.
Here we have a basic philosophical difference. Sure it's possible to shoot a shotgun at game at very long distances and have it drop dead, but some of us are reluctant to rely on sheer luck in these matters and prefer to only shoot when there is an overwhelming probability of a clean kill. With deer and buckshot, that's going to be at short range.
