I shoot the exact same set-up and I'd strongly recommend that you go with saboted ammo. Like some of the others here said, tho, you need to try several to see which one works best for you. One bit of advice I can give you, tho, is that it is my opinion that there is no need for you shoot a 3" shell. I've noticed no differnce at all in knock-down power, but I HAVE noticed decreased accuracy at the range with 3" shells. I think it may be partly due to me dreading the recoil so much, but why suffer when the 2 3/4" shells do the job? My gun likes the Winchester 2 3/4" shells best. Also, if you dont have time to go to the range to fully test several different brands of ammo, you ought to know that you should be able to get "pie-plate" accuracy with just about any sabot out to 75 yards minimum. Good luck!!
