I guess every gun is different my friend! The Remington Super Full has been the best in my 18.5” barrel 870. Some cheapo Tru-glo .565 has been the best in my son’s 21” barrel 870. We shot all three of those Indian Creek constrictions I mentioned in 3 different short barrel 870’s back then and none of us went forward with an Indian Creek for hunting based on the pattern performances. Which we found odd because all of us has been hardcore Indian Creek guys up until then with the swap to TSS. Of the three constrictions we tried in the Indian Creeks, .570 was our favorite. .555 would sometimes give a way too tight core and then sometimes it would totally blow the pattern. We were not impressed at all. That was with Hal’s 1 5/8 3” load (big 20 XL) and straight 9’s. I have never looked back since. Aint changed a thing in several years now.
