With respect to Dugaboy1, I take issue with, "...the tiny palls that are required to extract the rimless cases are break prone..."
You make it sound like "tiny palls" (sic. pawls) can be relied on to break A LOT? Have you evidence of incidences to support this with regard to double rifles? You make it sound like a double rifle with pawls is unsafe and unworthy.
Is this a biased opinion you have against pawls in general?
First let me comment on your quote above! You are intitaled to your opinion, but let me ask you one question. First what brand are these two double rifles? How long have you owned the rifles you claim, and how many hundred rounds have you shot through them under the African sun, and in the African dust, or in the cold of Alaska? Or is your post simply an opinion based on nothing more than what you hope will turn out to be as you think when you actually buy these two double rifles?
Now to the pawls issue! The pawls are not only break prone but are jam prone as well. A tinny amount of the very fine African dust that gets into everything mixing with oil in the slots the pawls are fitted in can and does on occasion jam them in the down position. Also the tiny springs that work these things are very fragile as well.
I own a High Grade 416 Rigby double rifle with pawls; mind you they are not worthless, as depicted. My pawls don't break nor have I had one fail to catch and extract a case. In fact, I can't get a casehead to push past the spring pawls.
I’m sure you own a HIGH GRADE DOUBLE RIFLE chambered for 416 Rigby, and I’m sure you have used it in the conditions where it is exposed to 115 degree heat, and the dust of Africa, riding miles of dusty tracks in the bakki, then pushing through jesse that is as thick and dirty as any place one can hunt, and I’m sure you have never had a malfunction under those conditions. And your last sentence in the above quote points out another of the draw-backs to rimless, and belted rimless cartridges in a double rifle. Having to PUSH the rounds into the cambers rather than simply dropping them in the chambers, and closing the rifle. If your HIGH GRADE double rifle has ejectors and they work then fine, but if it has extractors, then the cases must be plucked out of the chambers rather than simply being dumped out by raising the rifle’s barrels up.
If you like a flanged-type cartridge then by all means PAY FOR IT! However today, belted, non-belted, and rimless cartridges "all" work in double rifles. Unless you are a qualified firearms engineer opinions are just that ...cheap fodder. People should not cast dispersions on calibers and firearms that others have found to be a fine personal choice.
Again flanged cartridges cost no more than the rimless chamberings, so I do pay for it, and the “TODAY” you mention is smoke. Even if your double rifle as made yesterday, it is still 19th century technology, and is prone to the same conditions in operation as a 100 year old double rifle with the same features. I am not a firearms "engineer", but have built my own double rifles on three occasions, owned over 35 different double rifles, from 22 Hornet to 577NE, in the last 52 years since I bought my first one in the spring of 1958 when I was 21 years old, and have hunted them on four continents for every thing form hippo and Cape Buffalo down to black-tail jackrabbits, in every kind of weather from 40 below zero to 118 degrees above, and from snow to the thickest dust, and bush known to man. I think I have some experience with double rifles, and what works, and what doesn’t. Of course evidently not as much as you, according to you.
As in all hunting, one needs to fit the bore-caliber best suited to the game being hunted and then consider the best type of action based how quickly one needs a second shot. I doubt extractor pawls are the nemesis being portrayed. Anyone spitting on them here probably doesn't have a double rifle with them anyway (obvious from the spit).
Son, you can’t name a type of double rifle other than a bolt action double that I have not owned, and hunted with. As far as the second shot is concerned, one often needs more than the SECOND SHOT, and that again is another reason a rimless, or belted rimless cartridge is not a good idea in a double rifle that may be used for hunting dangerous game. O/U doubles, and any double rifle chambered for a rimless cartridge is very slow to re-load for shot three, and four, because the cartridges usually can’t simply be dropped into the chambers simultaneously, but must be inserted all the way into the chambers with your fingers, with the resulting loss of precious time. On Cape Buffalo two shots are rarely enough, and if he is headed in your direction, you need no hindrance to your re-load.
It’s likely pawls are no more critical than the possibility of developing broken trigger(s), bad primer(s), bad powder (duds), mud-plugged barrel(s), or "God forbid" any possibly that you lost your crucifix before going hunting. Anyway, in a Dangerous Game scenario you ALWAYS have someone to backing you up. Having NO backup is foolish.
“IF” the pawl breaks off it can jam the rifle closed, or prevent it’s closing! A broken trigger (on a two trigger double, the only way the should come) or a dud, hang fire, or bad primer, only effects one barrel, temporarily. While a broken pawl may put the rifle OTS till tools can be used to fix the rifle, or broken trigger simply turns your double into a working single shot.
Being backed-up with dangerous game in Africa is a matter of law, not your choice! However, stop and think for a moment, why is it acceptable to use an inferior, or ill appointed firearm simply because someone else is armed? What if the PH is the first one hit, leaving you to pull his nuts out of the fire? You don’t think it would be your responsibility to shoot a lion, or buffalo off him? Anyone hunting in dangerous game country should be properly armed, as if he were totally alone! Any reliance on others to protect your life is folly, of the first order!
Judging comments, the 416 Rigby is an inferior case design and it should be relegated to bolt action use, only. That's interesting when so many fine manufacturers have made them in double rifles, as well as in bolts. If it's a thump you need then the 416 Rigby has a lot more THUMP than a 375 H&H. I own both calibers, but I still use each according to the game hunted (pawls or NOT).
Nobody I know ever said the 416 Rigby is an inferior case design for any thing but a double rifle, and that has nothing to do with it’s “THUMP” as you call it. It is only that it is a rimless cartridge nothing more, and that applies to all rimless cartridges that will be used to hunt dangerous game in a double rifle.
A proper double rifle for use on dangerous game is first best suited to a Side by side configuration. Should have two triggers, should never be fitted with an automatic safety, and shpuld be chambered for a flanged cartridge of sufficient power for the game you are hunting or likely to come in contact with in the bush. The rifle should also re-cock it’s self after firing one or both barrels, and breaking it to re-charge one or both barrels! There are both break-top single shots, and double rifles that must be manually re-cocked if opened for any reason. The Blaser S2 is one such rifle.
Good Luck ARDENT, and throw a little salt over your shoulder when reading views tossed around here.
Ardent, the above sentence is good advice, but you need to know which views tossed around to take!
Ignorance is only a word that signifies that a person simply doesn't know something, and carries no insult to the person. However stubbornly rejecting the knowledge that corrects that ignorance is another matter all together.
Ardent you can certainly take Stoneman's advice and if the belted/rimless 375 H&H in a double rifle floats your boat, then set sail! My advice is to look a little farther down the road of double rifles and if cost is a problem for you, and it is for most, including me, then Merkel 140-2 chambered for 470NE or 500NE can be had at a reasonable price used, ot the newer ones that are now chambered for 450/400NE 3" Jeffery cartridge is a very good choice. but the rimless chamberings for a rifle that you may use to hunt dangerous game is certainly not a good choice!
The double rifle chambered for a rimless cartridge may work for years without mishap, and it may fail on the first hunt, but when ever it does, my prediction is it will be at the most inoppertune time! Murphy's law wouldn't have it any other way!
