The 7/8oz 12ga loads are great for practice, and clay targets. You can load up some 7/8 oz loads that will pattern better than some 1oz & 1 1/8 oz loads. It takes some work and adjusting but it can be done. Also if your a duck hunter you can make up 7/8oz loads that that have the same pellet count and speed of your duck hunting loads. (Makes for GREAT practice!)

The only things you have to watch are 1, crimp, make sure that the shot fills the wad enough to get a good crimp. 2, if you shoot a autoloader, make sure that it that there is enough pressure to work the action. (I shoot a browning gold and have not had any problems, with 7/8oz loads)

Good luck
