RE: Best shells for 12 gauge mossberg 500
I have a Mossberg 500 as well, and just purchased the tru-glo xx turkey choke. I was shooting very accurately with 3" remington Nitro turkey #5, but had better results with the winchester XX Turkey 3".
My Remington Nitro Pheasant #4's can just about put all pellets in a 1 liter pepsi bottle at 40 yrds. I am tempted to use these for turkeys, since I had a good shot pattern and its a eavy enough shot!
