So I've decided to start playing with my 175 grain NOE/Ranch Dog tumble lubers in earnest.
I started a load workup in my 4" GP-100 and made it up to about 12 grains of 2400 in a .357 case in front of a CCI SPM cap. Seems to leave a lot of unburned powder and the recoil - while manageable - is creeping out of the "rapid fire combat" category, and into the "slow fire hunting" zone. Not 100% sure of where I want to be yet - only that I don't want to be in the rip-snort, max load area, but I want to be well off the reservation of standard .38 loads as well.
Another concern is that my S&W's will chamber this bullet seated to the crimp groove in a .357 case, but the ogive runs into the chamber throats on my Rugers and doesn't QUIIIIIITE reliably allow "plunk" chambering without a slight shove.
Sooooooo. . .wondering if smaller charges of 2400 will burn cleaner in the shorter .38 case, or if you have a better "hot .38" propellant choice.
