I am thinking about giving the Hevi13 shells a try this spring in #7 shot. I have never used shot that small before through a turkey gun, what constriction do you think works best? I like the idea of better pattern density, and still being able to drop birds out to 40 yards.
What gun are you shooting? For Rem 870 go with a .660 Jellyhead. I think on #7 shot I would like tighter constriction. I tried the Hevi13 #7 out of my SBE II with a .660 Jellyhead. It was okay but I still prefer the MagBlend or Nitro 4x5x7.
I've thought about trying a Pure Gold choke but I'm just not crazy about changing my setup.
