don't shoot T size steel through a 101 trap 1st year with fixed full chokes,it ain't purdey. I believe it was about 1990 and steel was not required or at least used around Haines Alaska. The shop recived a couple of T size flats of steel for free from a vendor and of course no one would buy it so it was given away thinking it would be cheap to use in a get the bear out of the back yard gun.A couple of weeks later a friend came in and showed us that the cheap sheels were not all that cheap to him as his 101 trap was ruined.In truth that montycarlo stock on his gun hurt like hell and no one could shoot it good anyway.
