I would like to offer my comments on the 148 gr HBWC bullet. As said previously that were designed for mid range target work, shooting at both 25 and 50 yard bullseye targets. Originally they were were used in the S&W K38 and the Colt Target Revolvers with a standard loading of 2.7 gr of Bullsyye powder. Soon after the the S&W Model 52 Master semiauto came on the scene, that same load was used quite effectively with the bullet seated to the case mouth. I have shot 1000's of these rounds thru my 6 in Python and my 52-2 quite accurately in bullseye competition some years back. One other note, before the advent of decent hollow point bullets, many shooters were loading HBWC bullets backwards thinking they would open up dramatically and be effective manstoppers. I found them to either tumble or keyhole after 15 ft and difficult to keep on a 25 yd slow fire target however.
