Just want to make sure

Just making sure before this weekend when I have to go trap shooting this weekend that the ** in the **S on the side of my barrel means that it is a modified choke...I will save me from having to go find a modified choke for my Mossberg 835. The gun is a Browning.
 
I thought we had this cleared up last week ....

each barrel should be marked independently ....but if for some odd reason there is only one mark on the gun / **S - then it means both barrels are choked "Skeet" .... but there should be 2 sets of marks ...
 
Yes, i did ask this last week, but I used a caliper to measure the bore at the end of the barrel and it came out to me right at the numbers from browning that show it being a Modified???...anyways I bought a choke for my Mossberg 835 so im fine, i just really liked shooting that browning... So now that brings me back to ** meaning modified, and the S standing for it coming in the skeet set?...all I know is it surprised me that it measured out to be EXACTALLY a Modified choke. I even checked 2 more time just so i wasent seeing things.
 
They were both the same at approx. .731, which is right in the modified numbers for a browning gun…

The only fixed choke standard production O/Us, that I'm aware of, with identical chokes are Skeet guns. They are designed to shoot two targets at close range. Other target and field O/Us have a tighter choke for a longer second shot.

With respect to your 0.731 measurements, I don't know why you think they're in the modified numbers -- they are out of range:
A modified 12-ga choke typically has about 0.020 constriction, and a Skeet choke has about 0.005.
The standard European 12-ga* is about 0.725 and the US standard is 0.729.
If you subtract 0.020 from these you get a modified choke in the neighborhood of 0.705 to 0.709.
Or, with 0.005 you get a Skeet choke in the neighborhood of 0.720 to 0.724.

Browning's O/U manufacturing history is based in Liege, Belgium.[/SIZE]​
Your measures of 0.731 are more in the neighborhood of 12-ga (over-bored) cylinder bore chokes. You may have misread your calipers, and the actual measurements were 0.721. I wouldn't be surprised to hear of Browning Skeet chokes at approximately 0.721 (0.725 - 0.721 = 0.004). I don't see a similar misread that would result in modified chokes. Like it, or not, there's a high degree of certainty that your chokes are both Skeet.
 
K-Law, my friend, C.W.S. wishes his chokes to be modified, so he's misinterpreted the chart to fit his expectations. In reality, his gun has factory fixed chokes (otherwise the barrels wouldn't have a choke code). Neither the Invector nor the Invector Plus chart column is applicable, they are both screw-in choke systems. He should be looking in the Fixed Choke column. There, Browning's modified is 0.705 -- which is exactly what I postulated. :rolleyes:
 
"...that is only .003 difference. Very small."​
In the world of comp chokes, .003 is a significant number. I have screw-ins that are less that .003 apart and they definitely perform differently.
 
Hi Zippy. I see the fixed choke column for a 12 gauge that you are talking about. I failed to pick up on it being a fixed choke barrel. I also see threads on other forums say that a stamped **$ means a barrel has a fixed skeet choke.
 
On a fixed choke gun ....whether its part of a 4 barrel skeet set or not ....the marks all mean the same thing. So the **$ means the barrel is choked for "Skeet" ....not that its a modified barrel in a skeet set.

But where we might be losing you ...is you have to measure the bore of the barrel ( past the chambers --- and into the barrel ) .... and get a measurement on the barrel .....then measure the choke ...and calculate the difference ...which is the "choke". It really isn't possible to do that with a caliper / although like Zippy suggested - you can estimate it vs the US standard for a 12ga.

The measurement you're taking at the end of the barrel is only relevent - when measured against the inside of the bore diameter ( so you need a bore gague) ...to do it right / but I suspect all this is moot ....since its pretty safe to assume its a "Skeet choke" ...
