Got bored today so I loaded up 100 rounds of .44 mag. I used Hornady 240 grain XTP JHP behind 19.6 grains of Alliant 2400 and Winchester WLP primers. The OAL was 1.608" and the measured velocity averaged around 1343 fps. That's a full magnum load and gives 957 foot pounds of energy through the 7-1/2" barreled Iver Johnson (Uberti) New Cattleman Magnum.
That pistol has a tendency for the screws to vibrate loose at higher velocity loads, so I had to secure them with Locktite. The cylinder retaining pin popped out after 12 rounds. I was shooting offhand at a 12" square piece of AR500 steel plate, 60 yards up the hill. 12 hits out of 12 rounds, and the steel target has a nice ring when the slug hits it.
