Odd as it may seem, since moving to Washington state over 26 years ago I haven't been waterfowling (Pacific flyway ducks slug-fed compared to grain-fed Midwest ducks) anyway my attention was completely on upland birds. That may change this season, but I'm not familiar with using steel shot. My question is this: Can steel shot be used in a fixed full choke barrel? The reason I ask is that today I purchased a 870 Express for my son and when browsing through the Remington ammunition guide that came with it it said "Steel shot cannot be used in a fixed full choke". Recently I had bought a second barrel for my Remington 1100 that was a 30" fixed full that I had intended to use for trap and waterfowl shooting. Will I be able to use that barrel with steel shot?
