I bought a new Caldwell chronograph a couple months ago, so I figured I'd check some pistol handloads I worked up within the last year or two. I had two old Shooting Chrony chronographs, but there seemed to be a 30-50 fps difference in measurement between the two, so I got the Caldwell. It's a nice chronograph. It allows you to run a cable to your smartphone, and save the results to a text file.
First I checked some .38 Special wadcutters I loaded up back in 2019. They were 148 grain Harrison cast lead wadcutters, loaded behind 4.1 grains of W231 powder, WPS primers, and an overal length (OAL) of 1.240". I shot them through a 1964 Colt Cobra with a 2" barrel, the same model BTW, that Jack Ruby shot Lee Harvey Oswald in the gut with. The results were as follows, and all were shot from a sandbagged rest, at a range of 25 yards...

Next was some ACME 240 grain Hy-Tek coated .44 magnum that I loaded up, back on 05/13/20. I had loaded them with 7.5 grains of Unique powder, WLP primers, an OAL of 1.620", and a heavy crimp. Those were shot through a 1970's Iver Johnson New Cattleman Magnum made by Uberti, which has a 7" barrel. Once again, 25 yards from a sandbagged rest...

Next were some ,44 magnum Hornady 240 grain XTP Jacketed Hollow Point behind 19.6 grains of Alliant 2400, which I loaded up back on 1/11/20. You could really feel the difference between these and the low-velocity plinkers...

Next were some Nosler 124 grain JHP 9mm that I'd loaded up back on 3/29/20. I had loaded them with4.0 grains of Hodgdon Titegroup powder, CCI #500 primers, and an OAL of 1.138. I had worked up that load with a Glock 19, but they appeared to be to long to chamber in the Taurus. So I ran them through a 1950's Spanish-made Star Model B The Star is basically a 9mm in a Colt 1911 format.

Lastly was some 124 grain 9mm bullets that I had cast out of wheel weights, using a Lee TL356-124-2R bullet mold. They have an measured Brinell hardness of 23, which was measured on a Lee bullet hardness tester. The were driven behind 3.9 grains of Hodgdon HP-38 powder, WSP primers, and have an OAL of 1.164". Of course, they also wouldn't chamber in the Taurus, so I had to use the Star Model B, which I bought at a garage sale a few years back...
