Wes Pryornon mauser CRF??
Has anyone tried any of the non-Mauser style CRF rifles?
There is this action by Ed Brown:
http://edbrown.com/htmlos.cgi/...1.059478219716011935Also this one by Sako:
http://www.sako.fi/sako85_features.php Does the mauser claw still maintain any mechanical advantages over these systems?
Or are they too unproven to tell? Personally I think that anyone going full-out custom would go for a Mauser because it is a known action - the other two have recieved very little press.

Joe MillerWes, I can't say about the Sako because I haven't seen one, but I don't like the fact that the Ed Brown action is Cylindrical and the extractor looks like a poor comparison to the 98. I don't know what they are asking for the Model 704, but I bet Granite Mountain's actions aren't much more.

I also feel a flat bottom action would bed better for hard kickers - and any inherent accurizing ability gained from a round action is a moot point at best in a hunting rifle.
The extracter sure doesn't have the massive look of the 98/mod 70 claw.
I was just wondering if the 98 style stil hold a measureable advantage over the type show on the brown or Sako rifles.
maybe I should re-post in the gunsmith forum - or a mod can move this topic.

ShinzoWes, I had a discussion as to whether or not these actions were true controlled feed some time back. Since then, I've refined my understanding of this somewhat in lite of a thread on another forum about some CZ rifles with their non rotating extractors not controlling the round until it was virtually chambered. In my view a CRF rifle is one in which the round will ride up from the mag & be caught by the extractor well before it chambers. I'm still not sure it is totally necessary for this function to be performed by a non rotating extractor but not having examples of the others to handle I'm not going to go into bat over it. I will say that AFAICS, the Ed Brown extractor appears as though it should act as a CRF rifle even though it rotates with the bolt. It uses an extractor which seems to be almost identical to the one used by the M1a & M14 etc, it might even be the same??? Not sure if that is possible. The Ed Brown site is not bringing up their rifle pages for me but there used to be some pics of the bolt face on it.

Michael RobinsonI don't own either one, but I have examined and handled them.
The Sako extractor is well known for being quite robust. Many Remington 700 owners routinely swap the puny Remington extractor out for the beefier Sako.
The Ed Brown extractor appears to be even more robust - it looks much like the one used on the M16 rifle. Very big and sturdy.
These extractors do seem to me to provide the "control" element of a controlled round feed rifle. The cartridges come up out of the magazines and onto the bolt faces and are held there by the extractors all the way into and out of the chambers.
That said, do these extractors offer the "pulling" power of a full length, non-rotating claw? Hard to imagine that they do, but I don't know. I also don't know that that's such a big deal anymore, given the use of modern, high quality ammunition.
The round action does not bother me at all. The Ed Brown rifles are bedded like naval rifles on the deck of a battleship. I own an Ed Brown 702 Savanna, which is the predecessor to the CRF 704, and I can tell you that first hand.

Sport FultonHowdy,
I own two Ed Browns - Savanna and Damara, both in 300 Win Mag.
My favorite "actions"/rifles are M70 classic style(pre and post 64) and 03A3's - CRF the old fashioned way-I have way too many of both.
I bought the Ed Brown rifles for the design, workmanship, innovation and the concept of top notch components all put together correctly in one package.
The two Ed Browns are the most consistently accurate firearms I have ever owned-for me they have been perfect-I've been shooting for 47 years. The CRF of the 704 action works exactly as advertised.
Adios

Duane WiebeProbably nothing wrong with the Brown actions..except the extractor does not have the "undercut" that make a tough to extract brass act like a chinese finger prison...the harder you pull back, the more agressive the extractor on a M-98 "grabs"
Then there's this...IF a M-98 component fails, you can always find a part anywhere in the world

jeffeossonon mauser?
ruger mkII and RSM
winchester m70
enfields
remington 30s
CZ 550
Savage(ish)
winchester CRFPF -
shilen
the brown looks like someone cut up a pushfeed, just like the winchester crfpf
the sako is a sako .. it works, but does have little parts
nothing wrong with the mauser design, someone may want a different look... okay, great, but the design is sound and like a sledgehammer, doesn't REALLY have any room, in terms of extraction, for improvement.. and what little room there is, the ruger mkII CRF takes up, engineeringly

Some of the Winchester style safties are an interesting development, they do permit the use of a scope, but are they are as safe as the original flag?
Kimbers have CRF and a Winchester type three position safety

The Ed Brown rifles haven't seen much press because they are EXPENSIVE, $3600. Out of most people's league.
As for the action, I believe it is the best compromise for not having all the metal removed from the extractor side of the action as a 98 does. Less is NOT more...
ED Brown ActionsThis link goes right to the actions.
I do not own one of these, but I have shot one.
Damn fine rifle.
