Can I shoot steel shot through my DeHaan Shotgun?
The barrels on all our models are all chrome-lined and are compatible with modern commercial steel (and other non-toxic) loads. With regards to choke tubes, you should not use steel in our Modified, IM, or Full standard chokes. You may get bad patterns (donut pattern) and even worse, it is possible to stretch and damage the choke tubes (as steel does not compress or shift/flow as well as lead). This is especially true with the largest steel shot, frequently used to for geese. Steel stays very spherical and generally patterns much tighter than lead, so you can use one to two choke sizes more open and get patterns equivalent to lead. Improved cylinder works very well for most ducks and geese. You can purchase special steel shot chokes made for tighter constrictions than IC.
