Another solid vote for - - -
- - -the 158 gr. LSWCHP +P
I have a mild preference for the R-P version, but have no qualms about taking the Winchester. Never tried the Federal version.
This load was first catalogued by Win as the "MS" back in the late 1970s, I believe. Had a couple of good contacts/shooting buddies at firearms section of Dallas County Crime Lab (Southwest Institute of Forensic Science,) which was just upstairs from the medical examiners office. Those guys were very enthusiastic about what they called "The City Load," or the "DPD load." Worked well on every solid torso hit. Noticible expansion from two-inch revolvers, and classic performance from the four-inchers.
My Colt Agent is loaded with the R-P ammo now. I also provide it for house and/or carry guns for my wife, ex-wife, son, and daughter-in-law. I've also given cylinders full to a least four other friends. I DO try to practice what I preach, at least in this regard.
I will note that this load is a bit vigorous for full-time use in alloy frame revolvers. I check point-of-aim vs. point-of-impact, certainly, but do my regular practice with lighter loads. Years ago, I developed a handload with very similar trajectory and recoil for practice, and shot an M37 Airweight Chiefs Special loose, twice.
Best,
Johnny
