Waterfowl Choke Question

[WSU]

Many of the extended range waterfowl chokes (Carlson, etc.) state that no shot larger than BB can be used.  I often shoot BBB when goose hunting. 

Has anyone shot bigger shot sizes through these extended range tubes?  What is the problem with doing so?

I shot T's but after a box noticed worn grooves inside the choke,but it wasn't a Carlson but a Remington

The problem is that the shot will get restricted and build pressure in the barrel.
Guns with screw-in chokes are very thin at the muzzle because of the threads cut into them.
I would follow the manufacturer instructions and not tempt fate.
Especially with steel shot.

That being said, I shoot steel #2 through an xtra full turkey choke and I have been told to shoot nothing larger than #4.
No problems yet.

It can blow the barrel apart at the end or the start of the threads.  Seen it happen a few times.

I've always just shot a slightly more open choke and taken the manufacturer's word for it.  Sounds like there is good reason for the advice!

This is what a choke can do with to large of shot.

Also nothing faster than 1550PFS

I think this is a good policy.
I put the full choke back in yesterday, lol.

My uncle's 10ga auto had the opposite problem, blew the breech apart.

From the Carlson web site
Our Sporting Clays Choke Tubes are made from 17-4 stainless and precision machined to produce a choke tube that patterns better than standard choke tubes. These choke tubes feature a 25% larger parallel section in the choke thus throwing more consistent patterns than conventional choke tubes. Each choke tube is knurled on the end to allow for quick and easy removal. Each choke tube has the constriction laser marked on the end for easy reference. These choke tubes are backed by our lifetime warranty.

Lead shot, Steel Shot, Copperplated Shot, Nickel Shot, Hevi-Shotshells™, and Buck Shot can be used in our Sporting Clay Choke Tubes. Steel shot larger than BB should not be used in any Sporting Clays Choke Tube tighter than Full Constriction. Our Sporting Clays Choke Tubes will throw tighter/denser patterns than Flush Mount Choke Tubes due to a longer parallel section.

EXTENDED STEEL CHOKE TUBES
Our line of Extended Steel Shot choke tubes pattern steel and other non-toxic shot extremely well. These chokes have a longer parallel section allowing for less flyers and denser patterns. The chokes extend ¾” outside the barrel eliminating damage to your barrel caused by prolonged use with steel shot. The extended portion of the choke is knurled and the choke has a matte black finish. The Close and Mid Range chokes can be used with all sizes and speeds of steel, lead, or Hevi-Shot. The Long Range is NOT to be used with any STEEL shot larger than BB, or with any STEEL shot faster than 1550 FPS. If you want to use any of these loads use try Mid Range choke tube. Use the text below to help decide which choke best fits your shooting situation.

• Close Range: For use over decoys, ideal for 0-30 yards.
• Mid Range: For shooting situations 25-40 yards (Steel shot larger than BB or Steel shot faster than 1550 FPS should be used with this choke)
• Extended (Long) Range: Great for shots 40 yards and beyond

Myth.

[h2ofowlr]

Manufacture limiting liability.

Your right. I have been shooting hypersonic for 3 years through a kicks and a patternmaster think I'm in the neighborhood of 9-10 cases. No issues.

A Patternmaster choke is an IC constriction but because of the 5 raised posts or the raised ring in the new ones, it takes the wad out of the equation so the shot can stays together for very dense, tight and very short shot string patterns. With a Patternmaster, you don't have to worry about what you're shooting, except BC and BS.  Just go hunt with confidence.
Larger shot, especially at super high velocities doesn't compress(for lack of a better term) as easily as smaller shot when being forced thru the tight constriction area of some chokes. This is why some manufacturers don't recommend shooting larger shot thru tight chokes. It tends to expand the choke until it's about permanent in your barrel.
Larger steel shot patterns tighter than smaller steel shot. I shoot #4's steel thru a Patternmaster early season and for close decoying birds and switch to #2's or Hevi Metal for longer shots or late season heavily feathers birds. BB's aren't a bad choice for late season, long range ducks and tehn you don't have to change shells if a goose flies by.

I use a wad wizard supreme but always numbered shot.  Number 2's are a do all.
