12 Gauge Invector+ Choke Recommendations for 3" Shells?

[SumToy]

We have found that the 675 to 680 will shoot about anything you want to.    We even have gone bigger with the Do All choke that will shoot ANY shell you want to.  Steel, Buck Shot, and turkey loads.

I found an INV+ Preston Pittman "Star Dot" Choke, hanging on a store shelf.  I now own it.
.676-.682? in INV+

I started to pick up a JellyHead .670 in INV+, but I figured that I would always have that option available, and this was the only INV+ Star Dot choke I knew of in Central Mississippi, so I got the SD instead.

INV+ Preston Pittman "Star Dot" Choke, .676-.682?
3" Bronze Hevi13 1.75 Ounce #6
BPS with 28" Barrel, at 55 Degrees
159 Pellets in 10" at 40 Yards
I counted a few snowmen pellets as two hits each, to compare to my 870's numbers from last year, with the same shell.

BPS at 55 Degrees with INV+ Star Dot in 28" Barrel = 159
870 at 70-80 Degrees with .665 Pure Gold in 28" Barrel = 157
870 at 70-80 Degrees with .665 Indian Creek in 28" Barrel = 155

With Hevi13, the Star Dot is as good as anything else.

Last Year I got 280 hits with a Star Dot and a Hevi13 3-2-7 shell in the 870.
