I patterned my gun for the first time with these loads and i had bad results at 40, 20 yards wasn't bad but once I got some distance it REALLY opened up to the point I would never make a 40 yard shot. I'm using an 870 with a carlson's longbeard choke... I know people shoot these all the time with success so I know they work and I don't have a lot of options for shells around here
