Rifled barrel vs. Imp Cyl. for slugs
I want to get the best performance out of slugs, I understand a 22" rifled shotgun barrel can shoot 1oz. slugs acurately out to 200yds with only a 6" drop. And it's 1-2" high at 100yds. 12 ga or 20ga, both are really close. I'm looking for information and not saying any of the above is how it is with trajectoryof shotgun slugs.:)

Wanting only a 6" drop at 200 yards is a little unrealistic if you are going to hit anything at closer ranges. If the normal 12 Ga. Slug 1oz Slugger is zeroed at 100 yards they will have about a 30" drop at 200 Yards. Zeroed at 150 yards you should be close to your 6 inch drop. However this will create a problem at closer ranges. *Regarding precise Shot Placement! For the best performance I would recomend zero at 100 yards. And learn the amount of hold over for the 200 yard shots! I have a Remington 870 With a 20" Rifle Sighted Barrel and it is very accurate at the normal ranges. As far as the gauge I like the 12 over the 20 for deer.

rifled vs. imp cyl
Thanks sniper. I googled 20ga and 12 ga trajectory, and I was getting all kinds of "questionable" information on results of slugs. I'll try the way you suggest on my shotgun and ammo selection. I was wanting to see if a rifled barrel is worth the $150.00 purchase. I'm wanting to have a 870 Rifled barrell 20" if it's capable of extended accuracy and distance. I'd like to have one shooting out to 100yds with good groups, and no more than a 4" drop.

At 100 yards u can shoot 3" groups out of my 24" smooth bore barrel with a modified choke the longest shot I have made on a deer is 132 yards ranged

If your priorit is the best slug performance then go with the rifled barrel. Sabot slugs will perform well in a rifled barrel.

That would be a rifled barrel with a sabot slug, for hunting at the yards you are asking about.
You can do 200 yards with a smoothbore and a foster slug but it won’t be the best performance

Rough rule of thumb- barrel and projectile- only ONE should be rifled.

If you have a rifled barrel, use sabot slugs. If you have a smoothbore, use rifled slugs.

Very good rule of thumb.

I tried sabots in a number ot tactical Rem.870s, and had mediocre results, at best.

One of my guys had a rifled barrel available for his Rem 1100 tactical that he used for hunting, and it shot the sabots like a rifle.

Shortly after seeing that, I was able to convince the department to buy an 1100 tac with a rifled barrel for the SWAT team.

My intent is to use an 870 to hunt deer using slugs and getting optimal performance with either rifled or smoothbore. So far, it looks like a sabot out a 20" rifled barrel should give me the 100yd 3'' groups I'm looking for. Without alot of drop even at 200yds, maybe 6-8" ? And of course from there a massive drop begins. Shotguns are getting popular again on the smaller acreages, I'm cool with it at most public hunting areas. Thanks for the replies:)

I scopes an 870 with a rifled barrel, the best I can do is 2 inches at 50 yards, 4-6 inches at 80 yards. If I go past 100 they really open up. I've fed it about every thing, they all group about the same.
