Problem with 870 express super magnum 3.5 inch

[bluetick]

Has anyone had an issue with this gun not holding a pattern at 50 yards shooting a variety of buck shot. I have tried 00, #1 and #4. I average 2 pellets in a 2X2 foot target at 50 yards. Remington has replaced the barrel, however the pattern is the same. I have tried imp. cyl, modifed and full choke.

Have you tried different brands of ammo?

If so, send it back to the factory along with a shot paper target.
Write on the target all details: Distance, brand of ammo, type of shot, choke used, etc.

If possible send several targets shot with different brands and types of shot so they know it's not just one type ammo.

I tried Remington, Winchester and Federal shells. Shot a total of 5 boxes which turned my shoulder into hamburger. I have three targets which I will send along with the shotgun to Remington. The support staff seems to be very helpful, I hope the repair department does the same job. Thanks for the suggestion. I am new here and have enjoyed browsing the posts.

I have NO idea what could cause an 870 to shoot like that, especially with two different barrels.

Whatever, Remington will take care of it.
