There is a nice Webley and Scott SXS near here that has been for sale for several years. I always admired it. The guy has been asking around $1500.00 for it. Every time I see him at a gun show or go to his shop, he still has it for sale. It has nice wood and a BTFE. This gun has always had the same problem that you are having with yours. One of the barrels always ejects the hull whether it has been fired or not. That always kinda kept me from buying it. Hope someone can help with this problem.
