Yes, for sure.
well for starters, you need to know what a shotgun is. a shotgun, like any other firearm, uses a source of ignition to ignite a powder charge and launch a projectile(s) at normally very high speeds. a shotgun in general differs from a rifle or handgun because a rifle or handgun fires a single, bore sized projectile from each cartridge. a shotgun typically fires MANY projectiles from each cartridge (typically called shells when talking about shotguns e.g. "shotshell") a shotshell can be purchased with either a load of several hundred very small pellets (birdshot), or just 8 or 9 larger pellets (buckshot). this is what makes a shotgun a very versitile hunting tool. you can load it with the smaller shot and take small game (birds, squirells, rabbits) and then take that same firearm and load it with the larger buckshot and use it to take much larger animals. buckshot is also commonly used for personal defence purposes because of its incredible lethality and stopping power. another difference is that rifles and handguns come in many different "calibers" that term refers to the size of the bore as well as to the size of the projectile it fires. shotguns come in "gauges" that term refers to the size of the bore of a shotgun. some popular gauges for shotguns are 28,20,16,12 and 10. the smaller the number, the larger the bore of the gun. (28 is a smaller diameter bore than a 20, and so on) how do they come up with the numbers for gauges you might be wondering?? the number is simply how many bore-sized lead balls it would take to equal a pound.
This is a shotgun with an internal barrel diameter (called the "bore) of approximately .410" which shoots a shell which is about .410" in diameter. It is the only shotgun shell size that uses this convention. A 12 gauge shotgun, for example, does not have a bore of "12". A 20 gauge shotgun has a smaller bore than a 12 gauge and a 10 gauge has a bigger bore than a 12. Gauge size is based on the number of lead balls of the bore diameter which are required to make a pound (16 ounces). 10 balls, 12 balls, or 20 balls.
"They could match extractor marks on the shell, yes." If they don't have the gun and it's registered: Highly unlikely, unless it being registered they also get a spent shell casing with the extractor marks and firing pin indent on the firing cap. Also, if you don't "police" your brass, they have the shell casings at the scene, where there is likely a casing with your finger prints (loading the firearm) and possibly DNA (sweat or blood on the casing). Realistically though, if it's a standard shotgun, smooth bore barrel, and you shoot rifled slugs or buckshot and leave no evidence of the shell casings behind, they would have a hard time matching it to just the projectile part of it.

In short, it is a barrel designed to fire slugs. Some are smooth bore which are intended to shoot rifled slugs or buckshot, while others are rifled and intended for shooting sabot slugs only. This is a very good and trusted answer. lcj
Bore shotgun is the way forward.

Yes you can. The bore is the same size.
