From one Wingmaster lover to another, I'd buy these from Rogers @ $11.99 a box and give them a try, FEDERAL 12GA 2 3/4" MAG SHOK LEAD HIGH VELOCITY TURKEY LOAD. I'd suggest six shot. Two years ago I realized my Wingmaster had taken just about everything except a turkey and I needed to fix that. I used these in a 3" shell and was successful. Years ago I bought a replacement barrel that excepts screw-in chokes so I did use a Primos turkey choke. I'm sure you would be happy with the results. Good luck!
