Oddball shotgun for turkeys?

[Ironeyes969]

The cheap end of starting is probably a 3" 1.75-2oz lead #4, 5 or 6. Just about every shell brand makes one. Winchester Longbeard XR are very popular but XX or Remington Nitro have killed many many birds

Lots of folks swear by TSS nowadays but at $10-$20 per shot it's very expensive to be testing choke combos with.

If you live/hunt in an area that prohibits lead then the next least expensive would be a quality steel shot in similar sizes (obviously lighter payload) or bismuth or copper
