New 870 SM 26" Barrel Choke Shell Combo Question

[taylorjones20]

Hi everyone, new to the forum.  I purchased a new 870 SM earlier this year and I would like to know if anyone else has the new SM and what kind of performance you are getting out of it.. ?

I have a Jelly Head .660 and I have shot the Hevi Magnum Blends 5-6-7 and got 150 hits in 10" circle at 40 yards.

I read on Nitro Company that these guns are finicky and they have trouble getting a consistent pattern...

Anyway, anyone out there got one of these (2011 or newer) and getting a good pattern?

Thanks!

That's pretty low for a 3 1/2 Magblend with that choke.  The first thing I would do is polish your barrel according to the sticky above and re-shoot.  Most 870 SM's love the JellyHead .660, but not all, but you need to get that barrel looking like a mirror and then you can evaluate that choke.

Clean the barrel and shoot HEVI #7's through that JH .660 choke... you should be spot on then.

I would ditch the Jelly head and buy a Haymaker .670 made by Indian Creek.  You will get much better patterns.

I had this same gun 2 years ago and shooting both the 3" and 3.5" Hevi 7's thru a Jellyhead .660 consistently put close to 300 pellets in a 10 inch circle at 40 yards.

That's what I'm looking for!  I will polish the barrel and try the Hevi 7's

Thanks

My 870 with .660 shot the 3.5 7s pretty good. Just a clean barrel. Don't remember the count but I do know it was well over 250.

I've got the same gun, 26" barrel and 660 JH.  I shot mine the other day in 40 degree weather using 3 1/2" Hevi #6's.  I was consistently getting around 225 in a 10" @ 40.

I shoot the same thing as you do but with a polished barrel and I just got 262 a few days ago when I checked my poa.

This^^^ ALL DAY LONG.... also.. the turkey thug 3.5" 6's  put around 180 in a 10...

Thats major WOW Factor with lead!

We will find out shortly how good this Thug ammo really is.  I'm gonna have to see for myself what the 835 and the Star Dot will do with this stuff. 

And for the record my 870 28' barrel didn't do what I call well with either of the Jelly Head chokes.  They shot some turkey kill patterns at 40yds no doubt.  But they sure didn't live up to all the hype that folks are saying about them either.  I have found other chokes that would light the Jelly Heads up.   

Heck the Rem Ventilator .655 out shot the Jelly Heads in my barrel by a lot.  And you can buy this choke for $24 shipped to your door.

I have had similar results with the JH chokes that ILIKEHEVI-13 has,  my gun prefers IC .665 while my brothers likes Pure Gold .670.  It is very expensive shooting Hevi shot with this choke and that choke to find the magic combination, but eventually you will find the right combo,  keep us updated what works out for you. 

[ILIKEHEVI-13]

Mine shoot the 7's the best out a MAD Super Max .675 choke.  I also have a Pure Gold .670 that shoots them well.  The best Indian Creek BDS choke that I tried out of the 4 that Mike and Stuart let me try was a .669 choke.  I should of kept that choke.  But it still would'nt out shoot the Super Max which was made by Indian Creek as well. 

Now remember this is 3" 2oz #7's and not 3.5" 2.25oz loads which have more shot.

Here was the Indian Creek .669 choke.
