You didn't tell us the distance the targets were shot, but if you are only getting that many pellets in the circle then your pattern would be considered somewhat poor (unless you are shooting at 50-60 yards or further).

FYI - you mentioned something about #2 shot. Note that it is illegal in most states for turkey hunting.

Most top chokes are designated by internal diameter, not full or super full. Look on Indian Creeks website for more on that.Typical constrictions for 12 ga start at about .680 and go down from there all the way to .655. In general good results are had with .670 and .665. Mossburg 835 and 935 barrels are overboared and chokes for them are a bit larger.

The standard of pattern comparison is the number of hits inside a 10" circle at a measured 40 yards (not steps - use a laser rangefinder). The pattern needs to be uniform. Thedenser thebetter in my book as long as the pattern is uniform.Using hevishot will increase pellet denisity significantly over lead.

With tighter patterns comes the need for more precise aiming. Most people I know who try to achieve optimal pattern denisity use aiming devices more advanced then a single bead on the end of a gunbarrel. I use a low-power variable scope. Next year I might try a holographic weapons sight (HWS) by EOTech. Red dot sights are also popular as are conventional iron rifle sights.

I get nearly 250 hits in the 10" circle. That is considered pretty good, though most of the pellets are #7 hevishot with the Nirto Triplex 4X5X7 load. Those #7s will flat hammer a turkey out to distances you won't believe.
