Anyone had a problem with difficult extraction with the Estate SWAT Buckshot load? I went shooting today and had several Estate rounds that were quite hard to extract. No such problem occurred with Winchester AA, Remington 2 3/4" Magnum 1 buck, surplus GI XM162 (Winchester Vietnam-issue), or Federal H13200. Gun is my old reliable 870 Marine Magnum. It was clean when I started the range session. Nothing appears to be out of order and I finished up with 50 Winchester Light Targets without the slightest hint of trouble, as usual with this gun. By the way, the Estate load patterned as well as the Federal and shot to the same point of aim.
