Perhaps this is off topic, but let me share some data from today.
Winchester Super X2, 22" barrel, smooth bore, no choke.
From 40 yards, table, sandbag:
1. Remington Buckhammer, 1.25 oz lead slug, 1550 fps. Two groups of two at 2.75"
2.Remington Slugger rifled slugs, 1 oz, 1560 fps. One group of two at 3.25" and one group at 2". (hmmm)
3.Federal Vita-Shok, .75 oz Barnes Expander HP Slug, Sabot, I don't have the fps velocity. One group at 1.75" and one group at 2.75". Each time one slug was turning over and one was a clean hole. (What the ??)
I hope the relevancy of this data is that the groups are getting the job done without a rifled choke. Heck the rifled slugs and sabot groups were as good or better than the non rifled slugs
I did order a Carlson's rifled choke and will share the data after some testing.
Edit to add: Adjustable ghost sights.

Not meaning to hijack the thread but something I noticed when shooting foster slugs and sabots through my 1187, 12ga. smooth bore with a rifled choke tube installed was the direction of rotation of the rifling in the choke tube upon firing caused the choke tube to tighten to the point I was concerned if it was going to come out when I started to remove it. It finally started unscrewing but I was sweating it.

I have heard Remington has stopped manufacturing the Buckhammers. Buckhammers shot the best of any in my 20ga. rifled barrel and I hated to hear they have stopped making them.

Updated data with a Carlson rifled choke. Same gun and same shooting conditions.
1. Remington Buckhammer, 1.25 oz lead slug, 1550 fps. 2.25" group (better by .5") This is not a rifled slug.
2. Remington Slugger rifled slugs, 1 oz, 1560 fps. 1.5" group (Big improvement)
3. Federal Vita-Shok, .75 oz Barnes Expander HP Slug, Sabot, I don't have the fps velocity. 2.5" group with a third shot flyer. Right in the middle of my last data.
Conclusion: The Sluggers shot the best with a group better by .5" to 1.75" than the previous groups. The Buckhammers improved by .5". The Federal Vita-Shok was a push, slightly to a bigger group. 2.5" vs 1.75" and 2.75"
I will be using the rifled choke when deer gun season starts on 11/17.
Next I am testing my Rem 1187 smooth bore unchoked and rifled choke. Data to follow.

Foster slugs will work in a rifled choke tube or barrel until they get full of lead. Buckhammers will do the same thing because of the lack of the sabot and they expand when fired to engage the rifling. I thing buckhammers are getting hard to find because part of there design came from a lightfield pat.

Brenneke KOs at 50 yards. The left target is with the rifled tube in my Baikal MP 94

3" Remington Sluggers at 50 yards, left target is with the rifled tube
And the sluggers at 100 yards
There was a persistent left to right crosswind that day.
It seems that the rifled tube does improve accuracy, but whether or not the improvement is enough to justify the $50 or so cost of the tube is debatable.
