“I would think a bear round would be a 12 gauge sabot slug.”
Dosn’t anyony use rock salt loads any more to drive criders off?
Back in the day when it was kids stealing your watermelons - rock salt might have been good. Kids today stealing your whatever, or black bears - rock salt would be foolish.
If you’re a gambling person I suppose you could load the first round with salt and the second with buckshot (humans) or a slug (bears). I prefer to have it loaded with the heavy stuff right from the beginning.
