@BeeMaa ,
@One Day... ,
@Red Leg are the R8 extractors as similar to a 700 m16 modifed extractor as I am thinking, or vastly different.
For lack of having one to closely examine now, are your R8 extractors similar to the m16 or Sako style?
I understand exactly your question
TTundra and I do not think that it was answered.
I would say that the answer is: neither.
The Sako-style extractor tension relies on a spring loaded plunger:
The M16-style extractor tension relies on a spring loaded pivot:
The Blaser extractor tension relies on a very strong and quite heavy-duty external clip spring:
My personal experience confirms the experience of
BeeMaa,
Red Leg, Stuart at
Tally-Ho HUNTING SAFARIS,
dchamp, etc.: the Blaser extractor has been 100% reliable for me.
Regarding modern cartridges extraction in general, here is what I wrote in my recent R8 review at
https://www.africahunting.com/threa...o-months-500-rounds-review.60483/#post-719044:
"I am on record for observing that one of the reasons CRF and its characteristic big external claw extractor were perfected in the 1890’s by Paul Mauser, at the request of the German Imperial Army, was to prevent extraction failure of the pure copper shells loaded with black powder, that were notorious for sticking in dirty chambers after sustained fire. I reckon that brass shells loaded with smokeless powder resolved this issue a long time ago.
If a case gets stuck nowadays, Mauser claw extractor or not, the action itself is stuck, short of a rubber mallet.
I do not mourn a Mauser claw extractor on the R8..."
Regarding CRF feeding, I am on record for observing that the other reason CRF was perfected was to prevent 1890’s peasant conscripts who had never handled a bolt action rifle before:
1) to jam the rifle by double feeding and risk detonating the cartridge in the chamber with the tip of the spitzer bullet of the cartridge being rammed into it;
2) to load the rifle inadvertently by pushing a cartridge in the chamber and leaving it there.
I continue to appreciate the fact that in a true Mauser CRF rifle it is impossible to close the bolt on a cartridge inadvertently pushed in the chamber - and I only wish that no CRF extractor would be beveled to allow it to jump the rim of a cartridge already pushed into the chamber, as some manufacturers do. This would make it impossible to load a CRF rifle inadvertently, and to fire it accidentally.
Can one close a R8 action on a cartridge inadvertently present in the chamber? Yes. Is this an accident waiting to happen? My answer is that a R8 decocks automatically when the trigger group/magazine is removed to load it, and that a decocked R8 cannot fire. From the perspective of accidental loading and discharge, I therefore judge the R8 to be as safe as a CRF rifle…
Regarding double feeding, yes the R8 allows double feeding. From this perspective, the Mauser 98 design remains unsurpassed. Is this an issue in the hand of a seasoned hunter? Who knows...
PS: To emphasize the difference between Sako, M16 or Blaser extractor with a Rem 700 extractor, it may be useful to show a Rem 700 extractor. It is a very small piece of stamped metal located inside a recess machined inside the bolt head, Various iterations have come with, then without, a small rivet to maintain it in place. It has a documented history of failure with hot loads generating sticky cases, but it is not as bad as some would let you believe. My own experience with a Remington Defense .300 Win Mag Mk 13 sniper rifle civilian clone in which the shells of the Black Hills190 gr match factory loads stuck, was that it was impossible to open the action without a rubber mallet and that the tiny extractor never released its grip on the stuck cases...
PS2: as to R8 steel rings, FYI based on Blaser USA, these were discontinued by Blaser when they transitioned from R93 to R8.
