Triple W,
Here's what I've found to work best in my '72 OT 44 Colt, 7 1/2" bbl:
BP loads with ~26gr 2fg and a Big Lube 200gr bullet of about 30:1 alloy, any good BP lube.~815fps, accurate, lots of smoke and recoil. Sends my 3/8" thick, 6" x 12" steel bottles flying from 50 ft.
3.0gr Trail Boss under a Lee 429-240-2R 245 gr bullet tumble lubed with Rooster Jacket lube.~685fps, accurate, mild to shoot and they easily send the above mentioned bottles off the railroad tie.
Either load does the job, just depends on what I'm in the mood to shoot.
L.O.
