I loaded up some Sierra 135 grain BTHP bullets for my Garand last week and shot them today. The load is 47.5 grains of IMR 4895 in all different cases (tested in groups of eight) over a CCI large rifle magnum primer. The round was loaded to 3.245 OAL.
The load shot about 5 inches higher than the 150 grain Greek surplus load, cycled my Garand and ejected the Enblocs without any issues. It was pleasent to shoot, I fired 56 of them today before moving on to the 308 and 6.5 creedmoor that I brought to the range with me. I did not get beat up by the Garand like usual. It grouped well and I was able to hold the 9 ring with several Xs at both 100 and 200. I think I have found my load for the military matches this summer.
