Thought there would be bigger difference?

I have a ssx and primos tightwad for my 870. The ssx is .643 and the tightwad is .660. Now I shot both of these at 40 yards with 3" 2 oz magblends. Here are the results.

tightwad

Now correct me if im wrong but in theory shouldnt there be more than a 5 pellet difference? Base on the constriction differences.
213 best with the ssx and 218 best with the tightwad.

I gotta get a better choke for my 835 I get less than half of that at 40 yds 4,5 and 6s are all just a little over a hundred!

Can't always go by constriction. Every shotgun is different. I stuck with a no name stock choke and can get over 300 in 10" at 40 yds you just have to find the right combo. if oldgobbler.com is back up they have done the work for you.

perfect example that the internal construction is as important if not more so then the exit number.
