Rudy, I tried to follow your link, but could not find the gun you bought. Is your gun a sxs or o/u? I have a Husqvarna Model 51 hammer sxs 12ga. and have enjoyed it. The only combination gun I have is a Sauer 12ga x .43 Mauser (11,15X60R) hammer-cape. I bought it to use this Spring hunting Turkeys in an area with a good supply of wild hogs as a bonus target. It seemed like a good remedy for that particular combination of game and I plan to shoot a deer with it next fall. If you restore the gun to it's original chambering, ammo may be hard to find...I know this because I found you do not just run over to the local Walmart and grab a box of .43 Mauser rounds...Geo
