+P(1) to the information Saxonpig gave. According to my 35 or 40 year old S&W ballistics booklet that came with my model 15, a standard load 158gr lead had a velocity of 910fps, a 158+P lead had a velocity of 1050fps. It appears that today's +P load was yesterdays standard load. The old booklet also shows the 38spl 125gr jacketed +P bullets stepping out at 1350fps. About 95% of my reloads for my S&Ws are 158gr swc at the "old" standard velocity, or mabe a tad less, and have some to the old +P velocity. I can not afford to buy much factory ammo. I use these loads in my 15s, 14, 19, and the one J frame I own. And they are very accurate. Just some thoughts. Old 112
