My preference is Tamara's load, specifically Remington +P 158g SWC HPs. But my dept. mandates Gold Dot, so I'm currently carrying 125g Speer Gold Dot +P HPs in a M-37 Airweight Chief as an off-duty/backup.
I've popped two javelina with the Remington 158g load, and was impressed at the expansion (looked like lead nickles), but not overly impressed with penetration out of 6" from about 40-60 feet away, broadside. Both initial shots were found on the far side against the hide. (both coup de grace's, however, were through and through. Hm. )
BTW, I'm moving this thread to the Handguns: Revolvers forum.
