This article may shed some light on internal geometry for those who have never heard of it. It is not breaking news as the article is dated 2008. http://allaboutshooting.com/article_inf ... ru6nkb0q27Roost 1 said:Internal Geometry??
My point is the same restriction does equate to the same pattern results (shot count, how dense, POA/POI, etc etc) amongst the various turkey chokes today, many times because of the differences in internal geometry. Hope I was more clear in this effort of explaining what I mentioned in my previous post.
REN said:Andy is right, the exit diameter is really only part of the equation. The internal make up makes a different in conjunction with the exit construction.
take the SSX choke as an example. The exit diamter for a benelli gun in that choke is like .643 which is TIGHT but due to how the internal design is created it does not shoot as tight as a kicks or something else with a smooth design in the same construction.
Sumtoy, Indian Creek, SSX and Hevi chokes all use someone of the same design with minor modifications. the use a ring system to stop the wad rather then depend on the ports to do it. Where as if you look through a kicks or pure gold it has a smooth design using ports to slow the wad. Neither is wrong or right just the design they use to get what they determin as optimal.
all that said to get to the point that the exit diameter does not say all that needs to be said depending on maker, meaning a
660 jelly head may shoot a tighter pattern then a 650 sumtoy just due to design.
Well stated guys. That is why one .660 and another .660 can shoot completely different. There is more difference than the name on the package.
Everyone is free to believe what you want. Its your money spend it as you wish...Personally I choose not to believe the "hype" and the marketing schemes....I will guarantee you I can take a $14 Undertaker of the right constriction for a certain gun and it will perform within a few pellets of some other brand choke of same constriction. I have been doing this too long to believe any different..My point in all this is you do not have to buy a $75 choke to get 300 #7s in 10" circle at 40yds....And by the way for the ones that love the #7s you will continue to love them if all you shoot at is paper or birds in the wide open but as soon as you have some brush in the way you will be sorry if shooting any distance at all...Not trying to start an argument, but just wait and see. We were trying #7s 20years ago, it is not anything new but there is a reason they never caught on.....until people starting having pissing contest on who could put the most pellets in 10" @40yds.
