If you really want to find what your gun likes the best go buy 3 boxes of partition gold's, lightfield hybred exp's and a few more and try them. Make sure you have a good good recoil pad on your gun cause you'll need it. I have a remington 870 special purpose slug and shoot the lightfiled hybred exp's in a 4" circle @ 100 yards from a bench rest. They are also as devasting as they are acurate.
