Imo, IC is the best choke for pheasant.
That's a good point, private land birds are not as spooky.Interesting post Goose.
A specific choke may not be a "one size fits all" here though. Its dependent on what kind of shotgun, ammo, and the typical range you are taking shots at. For me, the IC is the most productive because I use high velocity lead ammo and most of my shots are at birds on private land within 30 yards. They don't wise up as quick as highly pressured public land birds do.
After you hunt them a few times, they get spooky. But that doesn't occur until about Thanksgiving for me. Public land birds wise up in a week or two. Part of my strategy every season is to not "over hunt" any spots.That's a good point, private land birds are not as spooky.
Another thing to think about is the actual measurement of your choke. Just because it is marked IC doesn't mean that's what you get. I have a Dickinson SxS that measures .003-.005 tighter than standard for every choke. The Cyl tube is .005 constriction, actually a tight Sk 1, the IC tube is .011, actually Sk 2, Mod is .0185 which is closer to IMP Mod than Mod.
With heavy #5 loads this gun patterns even tighter than the constrictions would project.
Dickinson is made by Akus in Turkey. I'm a retired machinist and CNC Programmer so I know my way around measuring tools. These measurements were taken with multiple trials using a telescope gage and precision micrometer.
The bores measure .6675
The Cyl tube measures .6625, .005 constriction. Sk 1 std in 16 ga according to the chart I have is .004. Sk2=.010
I/C tube .656, .0115 constriction, std is .007
mod tube .649, .0185 constriction, std is .015
I/M tube .6405, .027 constriction, std is .020
Full tube .633, .0345 constriction, std is .028
I typically run the I/C- Modified tubes when hunting wild pheasants with home loaded 1 1/8 oz 5s Kind of a light Mod/ heavy Mod combo
No idea. I remember a statement by I think Jack O'Connor a few decades ago that said true cylinder chokes tended to give a donut pattern, light coverage in the center. Said a couple thousandths constriction made a more even pattern.
I have seen posts by other Dickinson owners that their chokes patterned tight, so I don't think it was an accident.
Sure, IF you live in phez land and can go any time you want with lots and lots of shots a year. I would much rather wait and take the high percentage shot. But I only hunt wild birds a week or two a year and sometimes might only have a handful of shots a year. I'll shoot full and extra full. Over a point I'll try and plant my feet, take a breath pull up and shoot. Wild flushes are all instinct.Imo, IC is the best choke for pheasant.
I hardly ever shoot anything but mod. Maybe improved every couple years on in your face doves over a mojo.Sure, IF you live in phez land and can go any time you want with lots and lots of shots a year.

I have pounded chickens and had them still keep going. Shot one a few years ago that dropped both legs and dropped a 1/4 mile away in a winter wheat field. Old males can be tough birds and don’t really get much credit for being that way.I hardly ever shoot anything but mod. Maybe improved every couple years on in your face doves over a mojo.
I shoot 3shot through a mod at steel shot quail and drop just as many. We do have to track a few ,probably a third of them, it’s good for the dog it teaches them to tighten up their search.
May switch to improved mod and 5’s on chickens pulled some feathers and dropped a leg on one yesterday. Never had that happen before they usually have no will to live.
I believe a true 16 gauge bore is 0.662" or 0.663". If that's correct, then ole_270's Dickinson is just slightly overbored/backbored at 0.6675". Which would mean his 0.6625" choke tube is truly CYL. Overboring has become more popular, along with lengthened forcing cones (leading from chamber to bore). I believe the theory is that it helps improve patterns, particularly as the use of large steel shot has become more prevalent. I think.Why does a tube labeled "cyl" have any constriction?
