My 20" rem supermag loves a .660 Rhino and hevi shot mag blend or Longbeard #6. It also shoots both of the aforementioned loads pretty well with a cheapo truglo. For some reason neither of my 870s liked the jellyhead. Maybe I got a crappy jellyhead.

Shot it today with 4 chokes and 5 different ammos and it is still junk....The very best I could do is IC 665 with hvy13 #7s and that was a poor 197. that same choke was 130 with hvy 6s, magblends were only 180 and 134 with LB XR. Jelly head was worse with all those. no wind and the conditions were good. I cleaned it each time between shots and polished the barrel to a mirror yesterday?? this is the worst gun I have ever shot let alone owned and I have had several. any ideas before it becomes a boat anchor

May be a "dirty barrel" gun. My 11-87 with a rhino is that way. If not, send it away to be worked on or just send it away, period.

Don't stress over it anymore just send it to me. I'll at least pay for shipping....lol  ;D

Seriously, you should send it off and have it looked at if you are not pleased with it's performance. But 197 is not a bad pattern IMO. I don't know what numbers you are looking for but I'm sure that will kill all day long.

I had this same experience with my 870 Express Magnum. I tried most of the common lead loads through a variety of chokes with no success. Tried Hevi 6s and mag blends and they were good but could have been better. I finally tried a .665 IC and Long Beard 6s and that was the sweet spot.

Call William at Sumtoy and send it to him. He can get it rocking! :toothy9:

I had the same problem with a new 870sm. Sent it to my gunsmith and he did some major polishing on it. Rough barrel from the factory. He started with aggressive polishing tool and worked it down to fine grit. Came back best Pb shooting gun I have.

Ventilator .655/ win xx 3/2/6's

270's in a 10 with Hevi 7's. 3/2/7's

Could go either way but Bigspur or Longshanks could be right.  Just might have to burn a box of shells and find out.  My 870 shoots best after 3rd or 4th shell and stays good until about 8th or 9th and then it starts going down hill.

One of my personal current interests is nest predators and how a majority of hunters, where legal bait to the extent of chumming coons.  However once they get the predators concentrated they don't control them.
