Hello all, I've posted a thread before concerning h110 and over pressure signs in a smith and wesson 629-6 44 magnum with a 4 inch barrel. My current load I've worked up is 23.5gr h110, 240gr xtp, cci 350 magnum primer, starline 2x fired brass, coal 1.5925, heavy crimp, SD 19, ES 68, AVG Vel 1350, hi of 1386, lo of 1318, fired casings just fall out of the cylinder. Primers are slightly flattened but not to an extreme. I was wondering if these velocities are typical for a 4 in .44 or if maybe I have a fast barrel? I chrono'd some factory WWB 240 jsp today and the box says VEL 1180, my results were SD 27, ES 90, AVG vel 1309, hi of 1338, lo of 1248. Groupings of my handloads are clover leaf 5 shot groups at 15 yards bench-rested. Does anyone have similar results with their 4 inch .44? Will repeated use of rounds this hot damage my revolver? Possible round count before service is needed? I'm just looking for experienced opinions regarding my load data in my gun. I will be using these loads and gun for deer and elk hunting, as well as shooting steel (and annoying my shooting buddies). Thanks! Happy shooting!
