Negative, because that buck/birdshot would tear up the rifling. But you can change back to your smoothbore on an 870 in about 30 sec. Not that I hunt deer with a shotgun. But these copper jacketed HP core-locked rifled sabot slugs are a world apart from old style deer slugs. You've essentially got an elephant gun at your disposal--providing the elephant is within 150 yards. I use them for boar. Most of my shots at boar are within 30 to 100 yards. Just as a kick recently, I tried 20 rounds at a manhole cover at 300 yards and got 2 hits without compensating for drop...but best penetration/velocity would be less than 150.
I don't think so (not 100% on this, never heard this before), Shot is encased in a plastic case (Wad), the separates on leaving the barrel.
Check out Thompson Contender 410/45 colt barrel.
Exclusion is the old fibber wads, yes they are still used, Mostly in Black powder loads. I use both,
