I use the 870 Mag. 12 guage..and fresh out of the box..I agree ..It stunk..so I took an experts advise and bought the Gobble Dot sights from Cabelas to shoot it in for turkey.WOW!!!!what a difference..Then I put in my improved cyklinder choke and I was mouth opened in shock at the 3 inch groups at 100yds..I honestly could not believe the binoculars..I thought maybe it was luck so I kept shooting..I am very happy..At 50 yds they were tighter than 2 inches..I'm using it this year when I hunt in thick places.

I was using the cheap Walmart 2 3/4 inch WInchesters..they work wonderfully
