I am probably going to give a little more information than necessary but I have searched til I am blue in the face. I keep hearing about how well "those 870's" pattern. I can't get mine consistent. It is only chambered for 3" shells. I guess the original turkey special. It took several years and I eventually got comfortable with the old white hevi shot (3-2-6) hulled shells and a .655 kicks choke. I could get 189 (my personal best). Several years ago I purchased a case of the old Remington hevi shot 3-2-6 as my back up load. It was a good price. Last year was my last with the old white shell, may they rest in peace.
I have tried at least 6 choke combinations with the Remington hevishot and my best pattern is 98 in a 10" circle. I have around 7 boxes left and I am probably going to sell those. Chokes at my disposal are kicks .655, .660, .665, hevishot tube .662, hevishot undertaker, redhead blackout .660. I have ordered magblends 5,6,7 and 4,5,7. I am going to buy some straight 7's.
Please help me narrow down my options. Also if you know something magical to get those old Remington hevishot loads to shoot I am all ears. Also barrel has been deep cleaned.
