I am newbie on Old Gobbler member, bought 836 Ulti Mag Tactical Mossberg 12 ga 3 half inches shell and choke .695 look like not tight pattern but i never fire so and read on website about Indian Creek Turkey Choke is best pattern tight one..675 and plan use on Remmington Nitro #4 and Supreme #5 need your help before i decide to order this weekend :welcomeOG:
First, congrats on a great gun. You are right the .695 will not give great patterns. The #4 will likely not be very good and you won't be happy. The number 5 depending on the load may be good, but I would at least go down to #6 to really get the numbers you want. You don't need to go to the heavier than lead loads, but a change to #6 will improve patterns greatly.
The IC is a great choke in the MB, and I shoot one. I shoot an open .710 b/c I shoot handloads that can really be choked tight. I like more open for hunting. The .675 will serve you well no matter what load you choose.
I ALSO SHOOT THE MOSSY835 WITH A INDIAN CREEK CHOKE. I HAVE GOT MY BEST PATTERNS WITH THE 3" HEVI 13 LOADS IN 6 OR 7'S. I DID SHOOT THE WINCHESTER SUPREME SHELLS. THEY DID GOOD OUT AT 30 YDS. BUT AFTER THAT THEY WERE HORRIBLE. I GOT 160 SOMETHIN IN A 10" CIRCLE AT 40 YDS WITH THE HEVI 6'S AND 179 WITH THE 7'S. THE MOSSBERG KICKS LIKE A MULE SO I DIDNT GO FOR A 3 1/2 SHELL. U WILL GET BETTER PATTERNS THOUGH.
