Thanks Hunter.
Good info, thanks hunter!
That is a standard factory estimation but I have found out the hard way that what is stamped on the barrel is only right on the target about 25% of the time.
Oddly, if the choke is marked FULL it probably is, but most modified chokes are barely giving IC on the target and IC labels are placing way less than 50% of the shot where you want it.
BTW, me and Nate spotted some likely test subjects this weekend both on the ground and in the trees. I saw some of the biggest fox squirrels I have seen in 20 years! You would have needed the best full choke pattern available to reach up where those boys were playing! Some of the trees were a good 100 feet tall.
And we had masked bandits. Nate fought the Great Raccoon War of 2015 Last night!
Hope hunting was good......LOL
Was wondering if you would comment referring to your work in actually patterning different loads with different configurations of chokes.
I'm thinking the industry needed a "Number/Letter/term" to assign to a stamping on a barrel, in the industry....that was consistent as far as machine specs goes.
I don't think that "Kinda considered a Modified choke with #6 lead.... @ 60% pellets in a 30" circle at 30 yds, ....on Thursday in July @ 82 degrees, .....relative humidity @82 %, with a cross wind of 8.67 MPH from the SE"..... is a good way to mark a barrel......Bhohahahaah
Anyway bottom line....Pattern that sucker.... if you want success.
I have learned that guns are a lot like cars in that no two are exactly the same and have their own "personality". You can have to that have been produced side by side on the assembly line and one will handle differently, pump differently, cycle differently, and in the case of shot guns they will pattern differently. It is essential that equipment be tested to know what it can and can't do.
KyRat is spot on about those squirrels. I think that location will be kept in the back of my mind for bugging out since there was enough critters seen in one day that could feed a dozen men for a month. Not to mention great timber with all kinds of usage in mind. Great Raccoon War of 2015....... I don't know if it was really that great, I lost! I even gave them a watermelon as a peace treaty and they still came back with determination. Those guys were relentless, not even the guard dog made a dent in them!
Yep we had the required "blast" this weekend and I got to help teach another squid how to stay alive in the woods, but that is a whole separate thread.
Back in the spring I went wild on those pattern targets and changeable choke tubes and learned a whole lot.
The best thing was that interchangeable screw in tubes are fantastic and the cheap ones from the factory work just as well as the expensive custom made aftermarket units.
The other thing I learned was that when you start using shot of any size above #7 1/2 your pellet count in the percentage area goes down real quick.
There are not nearly as many pellets on any given target with a 55% pattern as there are with a 70% full choke load when 55% of the shot only comes to 100 pellets in 700 SQ/IN.
Not only do you need lots of pellets inside the 30" circle, you need them evenly scattered to insure that little bitty target you intend to be supper gets hit by several of the pellets.
At one point I set up to pattern 6 different cylinder bore barrels and found that most of them would have left me hungry at the end of the day just because the patterns were so ragged a rabbit could have run through and been safe standing in the center of the pattern due to the big holes.
I do not think the push for these riot guns as "survival" tools is doing anyone any favors in the real world. The guys that put full choke tubes on all those old single shot Stevens, H&R Toppers and 37 Winchester guns they were selling to the farmers and ranchers knew exactly what worked in the woods or across the barn lot.
I agree.....
I still get a kick out of the $80 buck H&R Topper, cut down to 18" then pay to have a screw in choke bored and threaded.....can't be more than $50 or $60 bucks......LOL.....then wind paracord around everything and put your PSK on the stock.....Yeah right.
One of these days I am going to look through the gear and realize that I have enough riot gun barrels that if I paid someone to thread all of them for choke tubes I could buy my own lathe with the money.
That is when I buy a used lathe and do all of them in one shot!
Then I will also have the ability to crown rifle muzzles properly, turn half round/half octagon ML barrels, thread muzzles for flash hiders, turn my own STEN gun receivers and generally raise havoc.
I do have one Mossberg tube that is a 20" vent rib and has choke tubes. It is one of the handiest guns I have. Short and handy with extra full choke capabilities or even rifled choke tube capabilities and it still fits in the guitar case.
The Mossy 500 is fitted with a 18'1/2 "Breacher" barrel (got the mossy and the 2 barrels in trade for a trade 870 rifled slug barrel)......Open choke....carried that way for butt covering fire if necessary.....still full stocked, but handy enough to fire from the hip and cover a lot of area.
28" ribbed modified barrel is with it....if hunting is needed.
The 870 12 ga, 24" turkey barrel with all the screw in chokes works for what ever I need it for turkey, duck, pheasant, grouse, rabbits and squirrels, if necessary ......my duck hunting buddies swear that you need a 30" barrel....yeah yeah yeah.....LOL
I don't tend to go with the normal flow on shotgun use anyway.
My Mossberg with the short barrel wears the plug in the magazine and I use it almost exclusively for hunting.
my home defense shotgun wears a 28" tube with screw in chokes and carries enough shells to last all day, should the need arise.
No side saddles, no ammo on the butt stock, no bandolier flapping around, just 11 rounds straight up the spout and any choke I decide I like.

We need to get this picture posting thing corrected. I posted this just as I have all photos for 8 years and never had a problem. Everyone else seems to be having the same problem too.
I have been having this problem as well......
If I do an edit, sometimes can get them back....or in this case I quoted you.....
PITA
It's a bug in the vBulletin software. Hopefully, when Chris loads a new version it will be fixed. Until then, the mods fix them as we find them. They don't always stay fixed, however.
Well Hunter I used your chart today and gave myself a happy surprise.
I am supposed to be off camping today but I woke up under the weather this morning and went to the DR. who immediately gave me two shots and two scripts and sent me home. Apparently he thinks I am sick.
Anyway, while stuck inside I got to examining a new toy given to me by my son to help finish out the collection of firearms that can only be described as "what Granddaddy came out of the Great Depression carrying".
This particular object is a '97 Winchester copy made by the Chinese. 20" barrel model, which was all either of us could find (granddads was a 26" modified) and I anticipated an open choke.
While doing my first real examination of the beast I found the top of the barrel engraved with 1893/97 12ga 2 3/4" M
Now that M is usually right where one would expect to find the choke constriction.
Under Doctor's orders to not go out shooting shotguns, so I could start counting pellet holes, I did the next best thing. I grabbed the measuring device and did a quick check and found the bore was not the .73 caliber of an open choke barrel but is in fact .71 caliber indicating a Modified choke.
I am now doing the "happy dance", since the last thing I need is another cylinder bore riot gun. Even with the short tube this one can be a practical game getter.
I now have a replica of the shotgun that lived behind the grandparents' kitchen door and I admired through out my childhood, and except for the lack of that last 6 inches of barrel length it is a pretty close copy right down to the modified choke on Grandpa's old pheasant gun.
Anyhow, thanks for the chart, it came in handy.
Good to hear....lot's of stuff printed, lot's of stuff tried.....once in while the pieces fall together....
I will have to say that is the best example of most all popular gauges I have seen in one place.
I still consider it a starting place, and even manufacturers shell will pattern different.
Guy had a range in the back of our favorite outdoor store, now long closed,...and sold loose shells from open boxes of shotgun ammo, where you could by shell by themselves...so it was possible to buy like 3 rounds, take them out back and test them out in your shotgun or even a shotgun you were looking to buy......Like $.25 cents apiece.
So a couple of handfuls and some newspaper, answered a lot of question and arguments.......LOL
For three years I worked in a gunshop in a major urban area. The shop was backed up to the railroad tracks, and I mean it was about 15 feet from the rails!
I would work on guns and get repairs done and take the hardware home to test fire the work.
Occasionally I would have an emergency rush job that needed a test fire and delivery before the end of the day.
I would wait for the train to come by, run outside and test fire the gun while the train covered the noise and get back into the shop before the train passed.
I don't think anyone ever caught on to what I was doing, and I am sure if they had I would have been in deep doggy-doo. But I had a job to do and had to get it done.
LOL...This store was located backed up to the tracks as well....but had a pretty good indoor range that was used by the LEO's for practice, as well as shop business.
Was kinda in a crappy neighborhood.....but the building was pretty secure.
Was broke into by guys breaking thru the roof in the range area....problem was it had steel doors, no windows, and with no ladder....no way out..Found them there on Monday morning.....Dumb criminal tricks.
Sounds like one of those bucket mouse traps but on a bigger scale.
