Hey fellows....Been a long time away from here! Read this great post all the way through.....As my name suggests, I'm addicted to turkey hunting.....I say that to say this....
I've done extensive testing for 4-5yrs. with turkey shot and many choke tubes. I started out hunting with a Winchester pump a .665" Kick's GT and Win.#5's. They were the best thing in the early 90's going, with 35yds effective range...
Kick's and Comp-n-choke were two of the best chokes going and are still in the top 5, IMO.....
With the advent of Hevi-shot came Dead Coyote and others experimenting with tungsten mixes. I am one who has to have the best shooting gun possible toting in the woods. All of my friends too kept evolving to non-leaded loads.
What almost all of us found was a need to open up the chokes from non-overbored guns, Remingtons and Winchesters, and even some back bored guns like Brownings. We all moved from .655-665" constriction chokes to .670-.680" chokes, namely a factory Rem. XFull. And today, I'm planning to shoot some handloaded Hevi-shot loads with .700" Carlson's Full on the business end of my Rem. 870. A friend is handloading these HD loads and suggests .700"+...
yotenaylor, Rich Cronk, and derbyacresbob, all seem to have experienced the same results as I and 5-6 other hardcore turkey hunters found when moving towards shooting the hard-hitting Hevi-shot/tungsten loads.
Now some may say I'm crazy, but I believe the best patterning loads going are by Nitro Ray Filigomo of Nitro Company. These custom loads are so expensive, I'm ashamed to tell that they are $6.00-$7.00/shell. His ammo is famous for him mixing shot sizes, such as 4x5x7's, etc.
Someone above mentioned better patterns with non-ported tubes, and I too am finding this to be true with Hevi-shot and Remington HD loads. Kick's and Comp-n-choke do not recommend Hevi-shot anyways....Some friends do still shoot it despite warnings from the company.
When I first started shooting Hevi-shot I was shooting at a target with a 2" PVC pipe target stand. Copper-plated lead shot would just glance off the 2" PVC. Then as I shot Remington's Hevi-shot and Nitro Cos., the heavier than lead shots completely penetrated the 2" pipe!! I could hardly believe it...
Now I have not and probably will not shoot any loads for yote hunting as they are too darn tough to get in close here in the east. But I just wanted to say that I've found Hevi-shot or any tungsten-mixed loads perform better at longer ranges (40+ yds.) with moderately open chokes versus tight turkey chokes. And by what I've read here in experiments with T's, BB's, 1B, etc., looks like Rem HD BB's would be what I'd buy to start out if I do get antsy to bust a yote with a scattergun! Thanks for all the great pix and such. I'm sorry the post was so long! gobblr addict
