I havea new remington 870 super mag, witht the factory super ful trk choke. I shot some Winchester 3.5in, 2oz #4, and some federal 3.5in 2oz #5. I paced off about 40 yards. It was kinda hard because we still have about a foot of snow. The target was a piece of card board cut 10in tall by 6 in wide. The winchester had 50 hits and the federal had 57 hits. The hits were spread out all over the paper. I looked at the tree i proped it on and found alot of the pattern to be to the left. Anyhow, is this a decent pattern, or should i keep working for a better pattern. I'm thinking about buying a undertaker choke and selling the factory choke. How does this pattern sound to you.
