Best .45 ACP round for black bear protection

[Granygudness]

If I chose to carry a 45 for bear defense, I would carry 230 grain flat nose solids or perhaps the 255 grain hardcast FN solids. Buffalo Bore and Doubletap make them both, Underwood makes the 255 grain, and Winchester makes the red45, a 230 grain. Other sources can also be found. FN solids give better straight line penetration than round nose ball along with a larger permanent wound channel.
