I was digging around in the closet today and found a couple boxes of shells. I found a box of Heavy Magnum #5, and #6 they say nickel plated lead shot. So I was wondering if shooting them through a lead shot only choke whould hurt anything? I also found a box of Winchester High Velocity Turkey Loads #5. I havent seen anywhere on the box where it says lead, does anybody know if they are lead or not? I was thinking about seeing how the 835 with the factory turkey choke likes these shells, till the ssx comes in. The only thing is on the Hornady HM it says best with Imp Cyl or Mod choke, so the turkey choke may not pattern to well. Thanks for your time and help
