I just bought a Cabelas Exclusive 500 Home and field combo. I want to practice with the SD barrel at my local range. The range says I can only use 4, 3, 2, 1 or 00 buckshot, no birdshot. The question I have is what type of ammo is good practice with that has low recoil? I think Walmart has different types and I was thinking of going there. I would also be interested in firing some high quality self defense loads I hear there are some that come loaded with discs and projectiles. Thanks, Howard
