Gentlemen;
I do not wish to burst your bubble or dampen your enthusiasm, however you apparently need a history lesson. The .375 H+H came out in 1912 and accounts for more firearms chambered in this caliber, every year, than all other calibers combined with a .33 bore or larger.
I do not wish to detract from the outstanding .375 Ruger, it is obviously a most efficient cartridge, but please, the new KING of .375. It's diapers haven't even had their first change. REMEMBER the .375 Wby or .378 WBY both going to make the H+H obsolete, didn't happen. Then there was the .358 STA going to make the H+H obsolete, didn't happen, how about the .375 RUM and so on and so on and so on !!!!
Do you honestly believe that if Ruger went broke tomorrow that any other manufacturer would pick up the .375 Ruger, I think not!! Isn't this REALLY the final test as to the worth of a cartridge?
I hunted last fall in Africa with a .375 H+H and my son hunted with a Ruger African in .375 Ruger. He used 260 gn Accubonds and I used 270 gn TSX.
We were both highly successfull and neither one of us lost any animals, great hunts!!! Please save your hyperbole on the .375 Ruger for 20+ years then tell me it's the KING, at best right now it's an illegitimate queen compared to the H+H.
This of course is only my opinion, but I'll bet dollars to donuts that I have fired more shells from .375 bore and up, than most who opine on this site and I'll pretty much guarantee that I have killed more animals in more places on this planet than nearly all of you.
As I said before it's only my opinion!!
