My kids gave the old man a Mossberg SA-20 Turkey Thug for Christmas, and it is time to get it ready. I have used the Primos Jellyhead on my 12 ga with the Mag Blend ammo and had great results, but this is a different ballgame. Are the Jellyhead and Mag Blend going to be a good combination for the SA-20?? I can find no references to this combination, and just wondered if anyone had tried it?
