Even though it's possible that a rifled gun will shoot further than a smooth bored gun; that would certainly be the exception rather than the rule.
Generally speaking, the rifling is for accuracy...not range.
And, generally speaking, a smooth bore would shoot further than a rifled gun; because it has less friction than a rifled gun does. That's why the M1 Abram MBT has a 120mm smoothbore; to obtain more velocity. To compensate for it's loss of accuracy, due to a lack of rifling; the M1 tank fires projectiles which un-folds fins upon exiting the muzzle.
A single, non-rifled projectile shot out of a rifled bore shotgun (specifically a slug gun).
Rifled slugs were designed for smooth bore barrels because they lack rifling. Sabot slugs are made for rifled bores but they can fire through smooth bores with loss of accuracy. I am not sure about rifled slugs in a rifled barrel because I think the bullets rifling can improperly connect with the bores rifling and you risk scratching the barrel.
Any non rifled slug. However for best perfomance you want a "saboted" slug.
Cannon?
A rifled slug can be fired from a smoothbore barrel with relative accuracy to about 100 yards. By relative accuracy, I mean that shots can be held in a 5 inch circle. That is about the size of the target zone on a deer. For a rifled barrel, rifled slugs should NOT be used, but sabot slugs can be.
The nonliving parts to an ecosystaem are- -water -soil -fire
"Cannon" is one.
I click in cannon but can't. :)
The legal minimum length of a non-rifled gun barrel in the united states is 7 inches.
A non-electrical fire would be one involving combustibles or fuels but does not involve energized equipment.
no it is not
I am fairly certain it is the rifled part of the barrel, not including the chamber, from the headspace ledge to the muzzle, and including any permanant non-rifled attachments to the muzzle. Therefore, a rifle with a fifteen inch barrel can be legal if it has a muzzle brake or compensator which brings its length to over sixteen inches.
