Post subject:  Re: Browning choke codes..

I just rescued a 1936 Auto-5 (serial number and proof code both indicate 1936) from a pawn shop, and it has a choke code of "-**" (dash before the asterisks). I found some older codes, which are different from current codes, but this was not listed among them. The barrel serial number matches the gun. The gun does have a Poly Choke and the vent rib also has a Poly Choke inscription. I have been assuming it was aftermarket, but I don't know when Poly Chokes came into being, and I don't know when some were factory installed. I am not concerned with value of the gun - it was cheap and I wanted some experience using a Poly, which I've never done before (although I won't shoot it lots). Just curious about the choke code on the barrel. Thanks!

If nothing sticks to teflon then how does teflon stick to the pan?


I can explain that. Teflon's chemical name is polytetrafluoroethylene. Diamagratically, it looks like this:
.F F
.| |
-C-C-
.| |
.F F

...where the C's are carbon atoms, and the F's are (obviously) fluorine. Now if you can imagine, the lower F's simply stick to the metal

_F_F_F_ F etc.

while your eggs simply slide around on top of the flat part of the upper F's.

Got it?

Glad to help. :D

Post subject:  Re: Browning choke codes.. Skeet

The above shows Skeet choking as **$. In the older Superposed, actual Skeet guns with larger skeet forends seem to have little variation in markings. However, in field style guns I have seen and owned guns that are marked $$ (with no stars). Also guns marked **S (with - thru the S rather than vertical as in $). I have always thought the latter to be an indication of "non-factory" work even if they measure correctly. That said, I do understand there was a period where Supers came into country choked M/F and they were "opened" in MO according to demand with some inconsistencies. Any other thoughts on Skeet chokes?

I've called the browning historian and specifically asked if they marked skeet barrels with the S and a strike through it. He confirmed that they had. I have some twelvette barrels that were marked as such and was curious if they were factory or after market modificaion.

I recently purchased a mid-sixties Auto 5. The barrel has two asterisks which normally would lead me to believe it is a modified choke. However, one asterisk looks like it belongs and sits directly in front of the "SPECIAL STEEL" wording and has 8 points. The second asterisk sits to the left of the first and a little lower on the barrel and has only 6 points. I have seen another Auto 5 with two asterisks and they (the two asterisks) were identical so I'm wondering if this barrel started life as a full choke and was modified (as in changed) by someone along the line.

I'll resurrect this. I have the same markings on a Twelvette barrel, not sure about the # of points though. My question is....are these the asterisks that indicate choke? This is on the right side of my barrel and I read that choke designation asterisks were on the left....

Does anyone know where constrictions are available for 16, 28, and 410 invector chokes? Some of the information I have seen is contradictory. Thanks and excuse me if I have overlooked this information in this thread.

I see IC listed here as **- and on some barrels that looks like a Modified marking of ** plus a dash which looks to be part of the makeup of "- Special Steel -" rather than a part of the choke marking.

Seems it would have been better to have set the dash before the asterisks, as on this gun, which if original indicates more variety in Browning's markings than is generally assumed:

I wasn't sure if this information was posted anywhere and I couldn't actually locate it easily on the Browning website, so I thought I'd put it here. Below lists the bore constrictions (in inches) for the Invector Plus choke tubes for current Browning 12 gauge shotguns:

Extra-Full Trap, .040
Full, .035
Improved Modified, .025
Modified, .020
Light Modified, .015
Improved Cylinder, .010
Skeet, .005
Cylinder, 0

When I saw MarlandS as the OP on this thread, I KNEW this was an old thread.

Don't know where Marland is today, but he was a nice guy, IMO.
