I'm curious as to why you think the .375 Ruger, and likely by extension the .416 Ruger are pitiful.
To me the case design makes a lot of sense, and I'm suprised it took so long for anyone to bring it out.
Had it been intoduced during the hay-day of Mauser sporterizing it likely would have caught on in a big way.
I don't have any prejudice towards the belted cases, quite the contrary.
I understand why we have available the offerings such as the Taylor rounds that we do, but really, what's wrong with the Rugers?
Moose Masher;
There is absolutely nothing wrong with the case design or caliber, I just do that to send Gatehouse into dervish fits.
My #1 son actually has one and used it in Africa a couple years ago with stupendous success, using 260 gn Accubonds. He made some very long shots with that combo, to collect some very nice trophies.
I designed and built a whole line of virtually identical cartridges about 25 years ago based on the 8 X 68 mm case, improved to 30 deg. Didn't go up to 375 but did go 9.3 mm.
The Ruger is the ballistic twin to the old wildcat 375-300 WM which is a helluva cartridge and does everything the 375 Wby does, another great cartridge.
The only reason I don't have one right now, or the 416, is the garbage Horn brass which is all that's available for it. Even the new Nosler loads will be in Hornady brass, so no help there. If Win, Rem or Lapua tooled up and made brass for them, I would have both in a heartbeat. My bets are on Norma if anyone picks it up at all, which would be better than Hornady but still not my first choice.
It is a marvelous cartridge, but unlike Gatehouse, I do not believe it will send the H&H into obsolecence. In fact, I believe we are seeing just the opposite happening already, 375 Ruger sales are waning and the 416 stumbled and fell flat out of the gate, so I really wonder if we will see either one of these in 10 years. Lack of the big ammo companies latching on to it has also been an indicator that sales, and the future are definately in question. It needs a Jack O'Connor style advocate to get it hopping.
