Shotgun Chokes, Need help

[livin4fishin]

Pretty new to shotgun hunting here. I have a few questions that maybe ya'll could school me up on. I recently got a Remington Versamax from the old lady for Christmas. The last 2 years, i have borrowed a friends shotgun to go grouse and turkey hunting. I am looking to get a couple chokes for the shotgun. I saw that the Versamax only accepts Remington Pro Bore chokes.

Question #1: When looking into choke tubes at the "add to cart section" it says what kind of shotgun it fits. Some say "Remington" and some say "Remington Pro Bore".... Are these different ways to say the same thing, or different designs altogether, and i need to buy Remington Pro Bore only?

Question#2: I have been looking to get a modified and full choke to have on me. I also have seen alot of Waterfowl chokes that come in sets but seem to be listed in terms of short range, mid range and long range. They seem to have the same affect as the common named chokes (as far as i can tell). Can ya'll help me out and shed some more light on this for me? Help guide me in the right direction? example of the waterfowl chokes I was looking at were the Carlson's Remington Pro Bore Waterfowl Choke Tube Set found here....... www.choketube.com/choke-tube-product-det...re-Choke-Tubes&mf=21

My understanding is that those chokes aren't  interchangeable.   I would get a modified for grouse and a Full Turkey choke for turkeys.  What choke does it have in it. Didn't it come with a set?  Most likely it has a modified in it and in that case I would just look for a good turkey choke.

It came with only 1 choke installed, Full choke. I know that i could make that work for what im trying to do, just trying to learn it all.

Most of the Waterfowl (long, mid range types)chokes are gimmicks to get you to buy them, be careful with the shells you use. The wrong choke to shell can cause damage to the gun, I've seen two guns put out of action because of swollen chokes and bulging barrels.
 I personally only use an IC or SK chokes and very rarely a LM for ducks and geese. My choke company of choice is Truelock, I also have Briley, Carlson, Seminal and a few Colonial. Well that is my

and to make it more complicated you cannot buy into  the  Cylinder, improved cylinder, modified, full, extra full, cause they have different diameters from different companies. The names "Turkey choke" are equally meaningless.
You must pattern your gun with your choke and your load to know what is happeninG.
But to step out on a limb. Modified is the most universally useful choke. Cylinder is basicly the 12 bore, improved slightly tighter, Mod slightly tighter, full extra full etc.
