I have an older model 870. Around 2004 model or so. I've tried a rhino 660 jellyhead 660 and my gun will not get near the high numbers with hevi 6s or the magblends. I tried just a plain rem super full .665 choke and got around 150 in the 10 at 40 with the magblends. A lil better than the jellyhead. Do yall think I may need to open it up a lil more and try some 665 or 670 chokes? When I shoot at 40 yds I have a lot of flyers 20"s are more away from my point of impact
3" or 3.5" ? The older 3" guns seemed to love the JH .660. I got great results with a JH .660 in a newer 870 SM shooting 3.5" Hevi #7's (334 hits in 10" at 40 yards) but I had to go to a JH .665 to shoot Lead...
I have a 3" 11-87 that loves hevi 7's out of a 660 rhino.
Always heard the JH .660s shot the Hevi shot straight 6s and 7s well. What kind of shape is the barrel in? Maybe a deep clean would help.
It could probably use a good deep cleaning. I have a new 870 supermag in bottomland. May just try it. It jus seems like it use to shoot hevi 6s and 7s so good with a jellyhead that's in it. A 660 but either hevis numbers are way down are my barrel needs some serious cleaning
Try Winchester 2 3/4 6 shot xx turkey loads in those 660 chokes.
Yea they are copper plated lead. I've been shooting them in my 870 for years with a Remington super full.
Remington duplex 4x6 is another Good one in lead for a 660 choke.
What length barrel does your older 870 have? And I can assure you that the JellyHead .660 in that 870 Supermag Bottomland will shoot lights out with the Hevi 7's and 6's. :OGturkeyhead:
Old barrel is a 26" and the new bottomland is a 26"

I believe Gobble! Is dead on with the deep clean. Maybe look up how to do it and polish the barrel. Makes a huge difference. Me and a buddy of mine shot our 870s both with a .660. I had a jebs and he had a rhino. I shot mag blend and he shot nitros 4/5/7 and put up 230+ everytime.
I have a 24" barrel on my 870 and shoot 3.5 inch Hevi straight 6's through a .660 jellyhead. I get 200+ in 10 @ 40 everytime. You probably have the right choke. Deep clean the barrel. A clean barrel makes substantial difference.
My 870 SM w/23" bbl will shoot crazy good patterns with a .665 Jellyhead and Hevi 6's or 7's. I actually opted to go with the Rem SF Hevi .675 to open it up a bit. It has worked out well for me so for. My cousin has an 870 SM w/26" bbl and his even shoots better #'s than mine with the Jellyhead. I'd bet your SM in Bottomland will be the ticket with the Jellyhead and Hevi's.

Here are guidelines for "deep cleaning" your bore. http://allaboutshooting.com/article_info.php?articles_id=282

660 is probably to tight. Now the Rem super full at 665 is a good choke and will out pattern many of the aftermarket chokes of the same constriction.
.660 is definitely not too tight. :OGturkeyhead:
Yea a .660 in a 870 is no where close to being to tight. Puts a very even pattern with hevi 6s and 7s at 40.
This is interesting. I wonder why the 665 beat both of the 660s since the 660 is definitely not to tight?
Now could it be that every barrel is different and while some prefer 660, others may prefer 665? Hmmm.
I have a 2005 supermag with a .660 Rhino and it shoots right at the published numbers that Nitro says. I would start with a barrel polishing, as that will do nothing but help you out.

I think that is a factor from barrel to barrel but I think it also has allot to do with what kind of choke it is. The internal aspects of the choke make a big difference. Kicks and Ventilator .655 shoot the best patterns out of my 870's, but when it comes to Indian Creek .665 provides the best results. There is also the variable that comes with barrels being in much different condition than one another. Allot of these barrels that are turning awesome patterns have been polished and are kept in amazing condition through deep cleaning and cleaning after each shot. It takes a process to get the gun to shoot that way in allot of cases. I have a rem 870sm that wouldn't pattern well with JH .665 or any other choke for that matter. Agressive polishing by my gunsmith turned it into a great shooting gun with Ventilator .655.

My exact thoughts. A clean barrel has got me 30-40 pellets, also do not disregard temperature ad it will have an efect on your pattern.
