Lapper, I use a Mossberg 500 with a rifled barrel to hunt deer. Personally, I prefer to use interchangeable barrels, so I can use a smoothbore for other game, like rabbits, squirrels, and eventually waterfowl and upland birds. It's very easy to swap the barrels. As far as ammo is concerned, I'm a fanatic about Remington's 2 3/4" Core-Lokt Ultra Sabots. They're 385 grains, and go 1900 fps. That's 300-500 fps faster than most others. As you know, you shoot sabots through a rifled barrel, but you shoot rifled slugs through a smoothbore. With the sabot slugs, you get better velocity, range, flatter trajectory, accuracy. I've killed two bucks this year with my Core-Lokts. I love them. The only thing is, they're a little pricey. I use open sights. Lightfield (sabot) slugs are good, but the recoil on them was just too much for me. Follow up shots were affected. The reason the recoil is different is because the Core-Lokts, as I said, use a 385 grain slug, whereas the Lightfield Hybred Exp use a 1 1/4 ounce slug. I think that's, like 546 grains. The velocity on the Core-Lokts is 1900 fps, as I said, but the velocity on the Lightfields is 1454 fps. The muzzle energy of the Lightfields is 2564 ft/lbs; the Core-Lokts are 3086. I'd also like to mention that I prefer a pump. They're workhorses. Also, racking a shotgun seems to help with timing. Anyway, that's my $0.02.
