Reverse Choke?

[Badger Arms]

Okay, I thought I'd heard everything, but I was researching the Polychoke II system that screws in in place of your factory choke tube. It talks about "Reverse Choke". It explains it here: http://www.poly-choke.com/instruction.htm.

So, essentially, it's a "spreader" type choke. I wonder what kind of dispersion this is supposed to give you? I cut the last poly-choke gun I had down to 18.5" years ago, so I can't test it myself. Any idea of patterning peculiarities with this?

No, but "spreader" chokes have been around since the Blunderbus, although that was more for ease of loading then patterning.

Used to hunt years ago with an old man who used the spreader setting on his Poly equipped Remington 11 for quail in the brush, and he did awful good with it!

Remington's 12 Gauge Skeet Rem-choke is a spreader.

Haven't tried it, though.

Remington's Skeet Remchoke has -2 POC. I see very little difference between it and a true Cylinder choke, or Remington's nominal +3POC Cylinder tube.

Spreader Loads, however, do open patterns about two full increments,ie, Full to IC. Try Polywad's Spred-R or build your own from components from Ballistic Products.

Well, I'm not looking to spend extra money on anything. I'd had a skeet load in my Home Defense gun (An 870 Express with a 21" RemChoke barrel). I thought that Skeet was inbetween Cylinder and IC, but I guess I was wrong. That was how it was explained to me. Skeet should be .005" constriction. As it turns out, RemChoke Skeet is, indeed, -.005" reverse choke. They have Skeet, Improved Skeet, Improved Cylinder, Modified, Full, Extra Full, and Uber-Ninja-Turkey-Extra Full. Why no "Cylinder" choke then? That's odd. Their "Improved Skeet" is, in fact, .002" constriction... essentially cylinder. I've attached a PDF of the info I found here: http://www.remington.com/products/accessories/gun_parts/remchoke_specs.asp

Mayhap they believe "Improved Skeet" is more marketable than Cylinder, Badger.

Some makers do have a skeet choke in between Cylinder and IC with 4 or 5 POC. There's no universal standard.

IIRC, Number Two has a Skeet choke in. Patterns old Estate 00 nicely.

I thought that Skeet was inbetween Cylinder and IC, but I guess I was wrong.

Usually, it is.

The only choke I've seen spec'd as more open than Cylinder is the 12 Gauge Remchoke.

I'm not making any claims about how much it spreads, BTW, just using the generic term "spreader" if it's "negative constriction." If you think about it, "negative constriction" doesn't make any sense.

Badger Arms,

In about 95% of the cases, skeet choke IS in between cylinder and IC. However, there are one or two companies that for whatever reason (probably marketing reasons) mark their chokes otherwise.

As for "reverse choke" it's simply a designation of a choke that is actually more open than cylinder choke. Whether this actually gives a larger pattern than cylinder choke is debatable. I've patterned some of them that do give a larger pattern than cylinder and some that don't give a larger pattern.
