Edgar:

I am trying to understand this effect.

QUOTE: ”…a cylinder bore will alter the direction and spread less than a choked bore…”

Can this mean that the “unbalanced force” that is absent with a cylinder bore gun as Dean’s be a tight choke constriction, that produces in comparison a diminishing-return, shot-confusing, "ricocheting”, dispersal of ejecta from the bore?

That's my take on it Russel and to my mind a choke bore is an "unbalancing force" in that the choke constriction upsets or unbalances the unidirectional travel of each pellet in the shot charge.

Here's another example of the far-reaching qualities of that little cutoff Lifter.
At Hausmann's there is that station waay out at the end of the field where two simultaneous clays come screaming out from way up there in the woods going from right to left. It is a six target station and I smashed 5 for 6 with that gun with no choke. I would estimate that to be easily a 40 plus yard shot... maybe more.

Larry Frey was with me along with a few others but I don't recall exactly who.

All of that, and my opinion that there is something special about Parker barrels. . . . as unscientific as it is.

The taper wall of the choke portion departs from the straight wall, and the shorter the the choke, the greater the angle. Yes, that is the unbalanced force (action/reaction) that shot which begins changing direction rebounding from the choke wall begins a disruption in the mass of the shot stream.
In a true cylinder bore, that shot mass is impacted by no unbalanced force, and tends to stay in closer proximity to the center line.
All of this is my conjecture, and I can be convinced I'm wrong, but what supports my belief is lots of pattern paper shows a shot density well tighter than Skeet 2, approaching modified. I never gave it enough thought but I am sure that wad type will have some effect as well. It simply makes sense, that in the absence of anything that will alter the shot direction as it travels down and out the bore, the total shot mass will continue in a straight direction.

All barrels shoot to a certain point of impact. I do have a gun with two sets of barrels; one being cut from 30" to 24", the other being more or less Imp.Cyl and Modified. I fully expect that if I draw a circle around the total pellets of the cylinder bore barrel, and then shoot at the same paper with a choked barrel, there will be new holes. Beyond some distance, this will, no doubt, be less noticeable.

I agree with all the comments about a gun without a choke(cylinder bore). They shoot better than should given all we have been told or read regarding shotgun chokes.

I just recently bought a 2" 12gauge sxs with 25" barrels choked cyl/cyl. At my regular sporting clay place(PeaceDale Shooting Preserve in RI), there wasn't a target I couldn't hit/figure out(even if I needed a few tries) on the whole course. This was with 3/4oz loads with the short brush wads.

Looking forward to getting this gun old back action straightened out. I did read/figure out another piece of information. It seems the lower grade back action guns had the patent date on the trigger plate and higher grade back action guns had that information on the tang. At least in these early guns.

A question Edgar...

Yes, thank you.

My most prolific day of bird shooting ever was at a preserve in Utah over pointing dogs. I was using my transition era 26" VH12 that I had XXX open the chokes to IC/MOD from F/F. It ended up being +.004"/-.003", so it's a blunderbuss on one side. By the end of our 3 days of unlimited birds there I couldn't seem to miss with that gun and even killed a rooster at 70yds(guide called the range)with one #7-1/2 pellet to the head. I pulled off a double on chukars that took off 180deg to each other and nailed a quail that rocketed past my ear requiring me to spin 180deg and take him going away. I think I was more surprised than the bird. One day I killed 54 birds with that gun and was feeling pretty deadly with it. I can't imagine ever having another day like that. I was surprised how effective the open chokes were on every kind of shot. I have two other Parkers that are pretty much if not totally 0 choked and both are deadly over pointers in cover, especially my 24" PHE16. For open country pheasant and sharptails and for pass shooting ducks, I'll take choked guns.
