Choke Constrictions

[Rapier]

Thought I would mention that you might want to look at the Briley site at the choke constriction chart.

I was reading an article on line from a shotgun journal that was printed about 3 years ago. The article was about chke constrictions and listed the 12, 20, 28 and 410 choke constrictions as listed by Briley. Problem is that the chart then and now do not jive. The old article listed the 12 and 20 as the same with the 28 and 410 being the same but different from the rest.

The current constriction chart lists the 12 by itself and the 20 and 28 together with the 410 by itself.

Example: If you were shooting a 20ga or 28ga modified choke it would be .015, not the .020 of the 12 and the 410 would be .012

Mainly cause the smaller the bore the more shot is beaten up by the bore. The 410 is really terrible. The 20 and 28 has a shot charge that is almost the same length while the 410 is way longer...the 12 being the shortest for all intents and purposes...at least according to bore size. Personally I have found the 28 patterns a LOT better than the 410...almost as good as the 20. I usually shoot the 20 ga in the 12 ga event in skeet. For some crazy reason though my averages are higher in the 20 than the 12 and I shoot the exact same shells and gun Well duh!! I have thought of using the 28 in the 12 ga and 20 but I shoot the 20 so much better.....well a half a point of so in my averages Need to practice a whole lot more this year..want to be AA class in all guns by this summer!

Skeet,
Thought the scattergun guys that shoot games should see that the previously posted data did jive with the current data.

I understand that a 20 has a smaller in diameter pattern but longer in length. So if your bird flight path is better estimated than lead, the lead differential will be taken up by the long shot string. Might be a crock, but I find that I can run on certin days 5 to 7 birds on sporting clays better with the 20 than the 12. Course the 20 is almost two pounds lighter and swings faster, so it is hard to have a definate answer.

I do love to shoot my 28ga barrels and when I find a course set up for it, I haul out the 410 barrels. Course it is more fun when you get a bunch of guys that show up with sub gague guns and you can shoot together.
Best,
Ed

Actually Ed the pattern is essentially the same size(roughly) in almost all the guages except the 410...just a little thinner. In the 20 it really doesn't make too much difference compared to the 12. The 28 a bit less so. Usually the chokes on the 28 are tightened a little so you have to point just a LITTLE closer. The 410 is another world unto itself. A skeet choke in the 410 can be as much as .012(averages.007-.008) where in the 12 it is usually .002 to .004. My old M-42 Win Skeet gun has a skeet choke of .013. The Briley chokes are usually a little looser that the norm as they have a fairly long parallell section. Briley chokes are usually very uniform and fairly dense for the constriction because of that reason. My K-80 12 barrels are Briley choked although I have never shot them if I remember correctly. The tubes are Briley's and are of course Briley choked. I have a pair of Briley 410 choke tubes for those tubes that are choked(I think) .012...and ol boy...if ya can point them right will absolutely smoke a clay target..even at 35 yds which is a very long shot for the 410 skeet load. I have at least 50 different Briley chokes that I have accumulated over the years. Have a couple of Briley choked 1100 bbls as well as a standard weight 1100 20 ga bbl I picked up for skeet shooting. Even my Beretta gas guns have Briley chokes. The benelli M-1 Super 90 I just picked up had a couple of riley chokes with it. Like I needed another Menelli but the chokes were a major selling point. I'm a sucker for decent semi auto's
