375 Speeds

Just for the record, I recently sold my 378. Decided the ultinate long range big animal gun is no good if you're scared (too smart) to shoot it prone or from other feild positions. Deffinately perfect for mowing stuff down off hand at reasonable range though. I have other big bore guns with open sights and Q/D scopes that are CRF. So it boils down to, any serious hunt it probably won't be the WBY that gets the nod. Too bad it was very accurate and fast.
My new fangled pressure meter was on the blink that day.I had to resort to the old fashioned method.
Perhaps next time I could borrow yours, which would be the same pressure equipment you used to ascertain that my pressures were high.

I used your chrono to determine that...
The old king- the 375 H&H requires a longer action.
The NEW KING of the 375's -the 375 Ruger- uses a standard action.
The .375 H&H works just fine in a standard length Mauser 98 action.
But it won't fit in a standard Ruger action, one of the reasons the NEW KING came to pass....

We got comfortably over 2500 fps with 760 and the .300 gr TSX from the Ruger Alaskan, even in the cold.
I think if you gave Hodgdon's new Hybrid 100V a try you might be pleasantly surprised. I haven't got my hands on a .375 H&H yet for testing (what is it about the word TEST that makes people reluctant to lend you a rifle?) but in the .375 Ruger and the .375 Ultra I was able to get 50 to 100 fps increase, so it's my go to powder now, supplanting H-4350. H-100V is small particle extruded with rounded edges, about half the length of Varget, and has a loading density that approaches ball powder. The burn rate is similar to Re-19, so the H&H case will be full, even with a 300 gr bullet's smaller charge.
H-100V was developed and is manufactured by St Marks Powder, a division of General Dynamics, and is part of a family of propellants of similar structure made for a full range of munitions from small arms to artillery. Based on measurements taken from the over pressure from air burst tests, the powder is reasonably temperature tolerant, even in the cold, something that the Extreme powders have not lived up to IMHO. While I am cautiously optimistic, how H-100V performs as a rifle bullet propellant in the cold remains to be seen, because large diameter explosive charges as used in the over pressure test tend to outperform small diameter charges. The selling point to the military is that H-100V produces higher velocity at lower pressure, a condition that is much admired in automatic weapons.

I guess I am missing the supposed superiority/benefits of the standard length action over a long action.
When I shoot a bolt action rifle I action the bolt to load a round and I don't notice the fractionly longer bolt throw of a long action.
If weight is to be part of the reasoning that is definately lost when you add the heavy barrel of the Ruger rifles so I can't see weight being a deciding factor either...
Less performance, action length is meaningless how does this make this combo the King?
the Ruger 77 Alaskan is as much the king as the 375 Ruger cartridge itself is. The compact rifle allows you to go into heavy cover with confidence, and the 375 Ruger cartridge enables high velocity with a 20" barrel, so reaching out 300-400 yards isn't out of the question with a good shooter.
all hail the king!

Well said, Bartell....
BTW, In your store, what have the sales been of the various .375 Caliber cartridges in the last couple of years been? (Rifles and ammunition?)
