So nice that many of the slug barrels are rifled.. The old days prior to...your Deerslayer barrels that were choke cylinder and not rifled...You just never knew where the slug was going to hit..

I remember a friend back in OH>>>>>>>>>>>>>>1963. He was hunting deer with a 12 gauge pump and punking ball..AKA Foster Slugs... I was with him on the hunt... He aims for the bucks shoulder, fires, and he hit the buck right in the head.. Blew one of the antlers off. He did kill him right on the spot...However.....Yes it so nice that slug guns are now rifled...
I have one of those smooth barreled Cylinder 20 inch shotgun barrels for my model 37. Yep it for the shooting down my hallway...
However I might give it a try for coyotes with a load of # 4 buckshot...Might be a real good tree stand gun when you know coyotes just might come under that tree stand on the way to the dying rabbit?

I think the original Ithaca Deerslayer smoothbore barrels were classified as "Improved Cylinder." But I could be wrong. I have a post-855,000 s/n M37 and the fixed choke mikes at .705, a full .024 pts. off from a cylinder choke which is .729. This is between 20 and 25 pts. (thousandths of an inch), making its choke restriction somewhere between a Modified and Improved Modified. Yet it groups Remington Sluggers very well. My barrel is from '68. My brother's M37 Deerslayer was purchased in 1975 and his smoothbore barrel mikes at .715, which is still a little tighter than Improved Cylinder.

Interesting Info...I got my barrel for my Model 37 about 1978. If mine is like you said not cylinder then it could turn out to be an excellent shotgun for Gray Fox and for all predator in deep woods like wood lots and such.. I will have to pattern it with # 4 turkey shot... Also I will have to look around here to see if I have some type of gauge or measuring tool that I can determine just what my barrel choke is...

That little barrel does kick like a mule...Maybe that is why the slugs don't go where they are suppose too...

Been my experience with big shot (#4 buck) the closer to "cylinder bore" you get the better you are. And if you want to shoot down hallways with finer shot I don't think you could find any better because you will fill up that hallway in a hurry.....unless you have a bowling alley.
