Choke tubes... what works for one may not work for another, even if the guns are identical, shooting the exact same loads. Kinda like two Corvettes sold on the same day... one of them is going to run the 1/4 mile much better than the other.

As far as Hevi-shot, (and I've read more on it over the last month than I ever read on lead), I'd try to stay with chokes rated to accept it. Surprisingly, the economical Truglo chokes are.

The Comp-n-Choke is a good product, but they do not advise its use with Hevi-shot. Here's a pic from their website showing you why...

Take note that the front bead is missing, which leads me to believe that more damage was done to the gun than just to the end of the choke tube itself.

From what I've found during countless hours of reading, and based on actual consumer reports, there is no choke on the market that shoots Hevi-shot as well as a Rhino. I imagine that you "could" by trial and error find a combo as good, but it would likely be cost ineffective based on known results.

The makers of Hevi-shot say... "Any choke tube that is manufactured from high-quality steel, such as stainless, should be acceptable for use with Hevi-Shot. Choke tube manufacturers such as Rhino, Patternmaster, Carlson's, Truglo and Trulock offer Turkey choke tubes that are suitable for use with Hevi-Shot."

There are others on the market as well. I've heard some say that since it's turkey we're shooting at, (at best a couple shots a season), that it won't hurt to shoot Hevi's. Personally, I'm not a gambler and will stay with chokes that are rated. I think you'll be safer in the long run.
