I have patterened the traditional nitro 3.5" 2.25 oz 4/5/7's and i am getting very good patterns from polished 870 SM 24" barrel with a .665 Jellyhead. I need to buy more shells ... would you recommend the Mega weights and should i expect similar patters to the traditional Nitro's? Plan to get same 2.25oz blended load ... also plan to call Nitro tomorrow, but i expect there are several members that have encountered this same dilemma. Thanks for any advice and i certainly plan to pattern the new shells when they arrive.
