Hi Gary,
I will try to be as brief as I can on this subject.
I presently own two 12 gauge shotguns.
A Browning Gold Hunter 3 1/2 inch magnum semi auto and a Remington Super Mag - which was one of the first Super Mags that Remington produced..

I also have a box full of choke tubes - which the Invector Plus and the Remington both has the same thread, but the Remington tube is shorter then the Browning / Winchester choke tube.

Most choke tubes start out at a minimum size and then gets larger by as little as .003 of a inch until you get to the inside diameter of a full choke. What all this means is that you should buy your tubes by preference and not by manufacturer - because in theory they all do the same job. Just that you want to find the one that works best for the round that you wish to hunt with.

What I am trying to tell you is that not all guns are the same and not all choke tubes are the same. By just changing one component - you change the whole way that the shell will react to the gun and the choke tube.

So to try to answer your question without much speculation or opinions, the only way to answer your question is to ask for more information.

In the case of my own opinions - as with the two 12 gauge turkey shotguns that I own, a Remington Turkey Super Full choke tube and a 3 inch nitro mag Remington shell patterns good in the Remington.

The 3 1/2 inch shells tends to produce a stringy pattern that does not pattern well in either of my guns with most of the manufactured shells. I have tried Federals, Remington's and most of the other manufactures offerings.

Now that does not mean that they will not shoot well for you or that your gun is the same as mine or that you should limit yourself to any one choke tube or any one choke tube manufacturer.

I have some Undertaker Choke Tubes that works just as well as the Remington or any of the other manufacturers choke tubes.
The only difference between one and the other is that some has a knurled nut at the top which does not require a wrench to put in and take out. Those are my favorites.

The ones that requires you to carry a tube wrench is a PITA in my opinion.
