Choke size for 870 21" barrel?

[Thanatos]

I just bought a new Remington 870 Express Super Mag with a 21" barrel and intend to shoot Hevi 13 3" 2oz. #6. I was looking at a JellyHead .665 but my local pro shop thinks that a .660 would be better because of the shorter barrel. Pro shop also suggests #7 but I want to make sure that I have enough point of impact energy at 40 yds or so - that's why I'm thinking about sticking with #6. Thoughts on choke constriction?

660 and Hevi 7. You will be very happy.

Are #7s still gonna give me enough penetrating energy at 40 yds or so?

The #7 will kill to 50 yards or more with no problem. Just get your POA and your POI to hit the same point and have a good time.  I took my biggest bird last year at 50 yards and my other one at 47yards.

C I too like the .660 with h13 3.2.7

Guess that's because I am the local proshop guy!

just tried the jellyhead 665 and got 216 at 40. got a 660 on the way to see if it will do better with the same load.
