There seems to be some interest in .375 H&H in DR. I'll keep this forum up to date with my experience with mine. I currently have a batch of really hot loads for my Ruger No 1 tropical .375 (300 grainer at 2600 fps) I've shot 40 rounds without a single stuck case or extraction problem in 92 degrees. I now know the gun can take full factory loads, however; the fear of damaging an $8000 rifle has lead me to workup a lighter load. The loads I was shooting were at 53k cup (Max). Hodgdon reloading manual states 78 grains of H414 gives 2543 fps at 47k cup. Barnes states there XLC bullets reduce pressure by 10% so 47,000 * .10 = 4700 which yields 47,000 – 4700 = 42,300 cup. If I reduce the powder charge to 75 grains, that should drop my pressure to about 40,000 cup or a %25 reduction and still get about 2400 fps. I have order the reloading equipment and will see how well it shoots with this load.
