Title: Choke Size question
Post by: salt n sage90 on December 21, 2023, 10:49:28 AM: My Benelli SBEII 12g. is now 20 years old and the stock modified choke has finally rusted out (no threads left).
I bought a choke tube online. That said improved cylinder on the product name, modified in the description, and 0.695 for the diameter.
On the choke itself it says 0.695.
Through research it appears to me that 0.695 would be a full choke.

Can someone definitively tell me what sizes go to what diameter?
Ive done some looking up online but there are alot of different answers and tables.

Post by: Henrydog on December 21, 2023, 10:58:17 AM: .035 is full.

.695 is the diameter of the complete choke itself....as in what barrel it would fit.

If you bought an IC .010 or .015 would be the restriction.

A Browning Choke is always looser than they claim to be. (Ie it says full but patterns like a mod)

Briley's cost a fortune and I have not noticed any difference in their performance other a cheap Carlson.

A well know trapshooter, Phil Kiner, says in his clinics and videos "you can shoot any choke you want as long as it is full"

Post by: salt n sage90 on December 21, 2023, 01:29:45 PM: Thats funny. I feel a little less like a moron now.
From what I can tell based on the table below its a full choke I bought, even though Jebs calls it their "mid-range". I think this is because they tout long range chokes.
Standard 12 gauge barrel diameter is 0.729 inches. The lower that number the tighter the spread. What you take off that number is the "Degree of Constriction." Looks like some chokes are rated by the degree of constriction while others by the resulting barrel diameter.

Thanks fellas. Of course now I need to buy a more forgiving tube so there is something left of these tight holding roosters and quail. $$

Post by: salt n sage90 on December 21, 2023, 01:37:09 PM: It was a panic buy.
I would like to actually put some paper up and see how it does. I never have checked pattern on any of my guns, chokes, or shells...

Post by: Henrydog on December 21, 2023, 01:39:03 PM: Also remember that a Mod becomes a Full with Steel. So the IC you bought is mod for steel. For upland you should be good. And I just have to say, I hate steel shot

Did you check out Skagit Arms before you ordered it up? They have multiple options to choose from. Patternmasters are behind the counter. Those have treated us well.

Good to know though. Ill look for a Modified or IC there.

Agreed. I’ve been running a Patternmaster Code Black Duck choke since last season. It’s been an awesome addition to the SX4.

Post by: metlhead on December 21, 2023, 04:38:59 PM: I've noticed no difference between stock chokes and aftermarket chokes in my guns. Also, constriction of pattern doesn't change more than 2% between steel and bismuth. I've got stacks of pattern papers from years of shooting for reference. Nice having a range in your yard. My conclusion is the aftermarket choke claims are a sales gimmick. The extended tubes are nice to grab onto though.

Post by: ducks4days on December 21, 2023, 05:41:14 PM: Chokes work better or worse with different loads too. Switching to a different shotshell with the same shot size and same choke can open or close the pattern up a lot.

My favorite combo was an 870 with a Carlsons IM choke and Rio #2 steel.
