It's a total bunch of crap! Read the owners manual on the shotgun you have. My old Mossberg 500 came with a full choke barrel and owners manual said slugs were fine. I've killed many deer using remy sluggers through that full choke barrel.Help me out with this one.——
35 to 40 years ago I was told {if I remember correctly},
at a hunters safety course, that if you ran a full choke
with a slug you’d be running the risk of blowing the
end of the barrel off? As the slug is to big to fit through
the full choke? Any truth to this or was a getting typical
cop/gun shop firearms advise?
Some guns owners manuals will tell you not to fire slugs from their full chokes......bottom line read the owners manual.
Foster/rifled slugs are designed to swage down in size as they travel down the barrel so they can be safely fired through many choke sizes with no issues. Again .....read the owners manual.
