What is the best type buckshots to use in a Remington 1100 semiautomatic?

You need to specify what you will be shooting and what gauge 1100 you have with what chokes??? If you are doing Clay sports, which one? Skeet? Trap? Sporting Clays? (all would have different answers) Hunting? What species? Duck/Geese not only need different loads, but require steel or non-tox shot as well. Upland birds? Turkey? Deer? (some states do not allow Buckshot, but only rifled slugs) Generally the best shot to use depends on your game and the choke you choose for that sport. i have a 1100 and use the long barrel for deer, i use 4 buck, and its seems like that holds the best pattern in any situation.
