I would stay away from the lead bullets that travel more than 1000ft-per-sec because of leading in the K frame can led to a crack in the Force cone.

The Barnes solid copper hp is all you need and you can get the Federal loaded factory round or buy the Barnes bullet and load it to the max. That will take care of 98% of the Bear and all the mountain lion in Colorado, New Mexico, and Utah area.

If you’re going north you need a more powerful round like 44mag otherwise you piss off northern Brown/grizzly bear.
