Yup. When I first started with the CHP we they issued 158gr round nosed lead +P+ .38spl (great for drilling a little hole thru bad guys, doing almost nothing unless you lucked out and hit something really vital). You could carry anything you wanted, .38spl or .357mag, as long as it was NOT hollowpoint. We shot monthly with match wadcutters, and as you say, if you can speedload them, you can speedload anything. To end this little jaunt down history lane, we only had to shoot what we carried once a year, and it was not a scored shoot. Great thinking, huh, practice with a pop gun load, then when it counts you get a real surprise when that hot mag load goes off. 'Specially in the dark. A number of years later that changed, a lot...
