thinking about finally breaking down and getting an 870
rifled vs smooth
what is the real difference
can buckshot be shot in the rifled and a slug in the smooth?
how does one affect accuracy and reliability etc
what are the effective ranges for slugs and the varieties of buckshot
and as dumb as this might sound
can it be used for all aspects of shotgunning
ie hunting skeet trap etc
Technically you could shoot the buckshot in the rifles barrel, but your patterns are gonna be bloody awful.
Most shotguns are effective with slugs to 75-100 yards, but the slug can travel quite a bit farther.
With buckshot, you have to pattern YOUR gun with YOUR load to see how far it will pattern. I use paper shopping bags. Start at 3m and the move the target back to 5, 10, 15, 20, and 25m. Once you get to where not all the shot are in the target, that is the approximate effective range of your shotgun with that load. Here is why - shotgun pellets can be lethal well past 100 yards. If you shoot at a target and not all the pellets hit the target, a stray pellet can go downrange and kill someone.
My Remington 870 Police model with a cylinder bore barrel is good with Sellier and Bellot 00 buck to about 15m, and about the same with Winchester Ranger about the same. I have seen some guns that are good to 25m.
