Help with 870 Super mag

[Newtgallapavo]

I have an 870 sps that I am trying to make into a shooter but so far it has been nothing but frustration .Ive tried several different combos of shells and chokes with mixed results but all of them are pretty poor to what im used to seeing out of shooter I currently have a black diamond IC in it. Any input appreciated

665 IC with nitros, mag blends, hevi 7's and 6's. All those are turkey hammers out of mine.

have u done any work to urs? I haven't worked the barrel over yet but mag blends shot horrible thru my .665 IC When I shot 6s they were a little better but still really poor. polishing the barrel in the am and should have some hv7s here thurs to try. mighty frustrated so far

I got lucky and got a shooter. No work. It likes to be clean tho. You may have got a bad lot of those shells. Mine are several years old. I usually shoot nitros tho. Mega weights and hevis both from nitro are rediculous at 40. You'll get er shootin, I'm sure.

I have heard a lot about it needing to be really clean each time with those 870s. I will definitely make er shoot or it wont take up space in my safe  appreciate the encouragement, this may just be one of those that takes a little more patience and a lot more $$$$  should no more by the end of the week

I have a new 870 SM....all I did to it was deep cleaned and put a Patternmater choke in it and it is hands down the best patterning gun I own.

Give it a good cleaning and see what that does for you.

Best of luck!

Make sure your cap is not coming loose. Other than that. Give er a good deep cleaning.

The jelly head .660 and Hevi shot .662 choke both patterned better than the I.C choke for me. With that being said this years run of H-13 shell's 6's ,7's and mag blends have not patterned very good for me either. I have some from a couple years ago that put up way better patterns . H-13 changes there inner components every year it seem's.  I'd Try some Win. long beards and see how they pattern with the I.C choke .

Mine loves the Rhino .660 tube. It will shoot Mag Blends and loves Winchester X-tended Range #6. I have deep cleaned only. The Mag Blends will put 230 ,give or take, in a 10" circle at 40.

How old is the gun?

I would imagine a .670 Rhino with Nitro's would get you the performance you are looking for...
A .665 IC should put up good numbers as well though...

[Huntaholic]

660 rhino and nitro hevi shot is what works best in all the ones Ive owned and patterned for others.

[Bigspurs68]

This is normal for mine. It'll do better if it's real clean but this is good nuff.

I get great results in my SM with a Jellyhead .665 and 3.5" magblends.

Had one a few years back and experienced the same trouble you're having.  Ended up trying a Kicks GT .655 and it was awesome.  Couldn't find a shell it didn't shoot well with that choke.

spent a good deal of time today working over the barrel, deep cleaned it and polished it up nice I got my box of hv13 #7s today too but it was way to windy to try it out. Have 3 chokes and 5 different ammos to try tomorrow provided the weather cooperates. Will post results as soon as I get it shot. thanks to everyone for the advice and help
