RE: Best shells for 12 gauge mossberg 500
I wouldn't suggest using any shotgun. Who needs a shotgun, when you can use a 7mm-08. I would suggest using maybe the 175 grain, but they do say that the 100-125 grain works the best for the best results. Why use a shotgun, when it can only go about 60 to 70 yards at the most, when you can use a 7mm-08, and reach out there and give them a nice kiss with that bullet. And plus if you use the 7mm-08, you don't have to waste your money on calls or decoys, but instead on other things. But yeah i would recommended the 7mm-08 over any shotgun.
