Hello all,

A question to check my understanding: I saw the other day that Ruger has or is about to launch their proprietary .375 Ruger cartridge. In their efforts to match the venerable .375 H and H albeit in a standard length offering won't they have to crank up the operating pressures? Is this desirable? On a related note, my tattered copy of "Cartridges of the World" has a section in the back where it discusses the new offerings by H and H; namely the .400 and .465.

If I read it right the essay suggested the .400 was a development of the .375 existing case with the neck brought back so the projectile would not invade the powder chamber and it would also offer a secure hold to deal with the elevated recoil levels. It went on to note that H and H was getting chrony readings of approx 2500 fps "reflecting the potential within the old cartridge". Again, does this mean the existing .375 case can create higher velocities with say a 300 grain bullet? Thus, if the case can launch a bullet fully 1/3 heavier than a standard 300 grainer are they raising the pressures to do so? Again, is this desirous for intended applications?

Finally, I am involved with a custom project whereby my dad and I are having a matched pair of rifles made and we are traveling to NH, USA this weekend to the Empire Rifles headquarters to inspect two actions. I will report on this next week.

Merry Christmas!

Jeff
