It really is CREBB and not CRF

I was taking a look at my Win Model 70 and other other Mausers today and working with some dummy rounds as well as my Remington 700s and notice something interesting.

The "CRF" actions, that is the famous claw extractor, do not have control of the round until about 1/3 of the round is already well passed the feed ramp and into the chamber.

The PF Rem 700 round doesn't release the round form the magazine rails until the round is well past the feed ramp and into the chamber.

In other words the only real advantage is if you decide between 2/3 of the way through forward stroke of the bolt and up until the battery point to change your mind and pull the bolt back you wil get a positive ejection on a CRF.

God knows when I am in the field I always decide 2/3 of the way thru the bolt stroke to not chamber a round

I think I will start a petition drive to have CRF changed to CREBB for the sake of truth in advertising.

CREBB equals Controlled Round Ejection Before Battery

And yes I am just stirring sh*t today

Legistine actu quod scripsi?

Never under estimate the internet community's ability to reply to your post with their personal rant about their tangentially related, single occurrence issue.




What I have learned on AR, since 2001:
1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken.
2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps.
3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges.
4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down.
5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine.
6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle.
7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions.
8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA.
9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not.
10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact.
11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores.
12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence.
13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances.

Keep stirring Mike.
The CRF guys can keep talking and I will buy the push feed M70s. For paper targets, pests and prarie dogs I much prefer a push feed.

W/ a CRF rifle, the cartridge is either in the mag box or it is not, no different than a PF. When properly working, the cartridge case head will fully snap up under/behind the extractor claw as soon as it clears the mag box. Depending on the manufacturer, the cartridge, the gunsmith, etc., you'll find that some CRF rifles will drive the cartridge out of the mag box faster than others. As an example, I have a few well tuned M70s that drive the cartridge out of the mag box very quick w/ the claw extractor grabbing the case head w/ very little bolt movement. I also have magnum length actions from different manufacturers that do the same thing but just at a slower angle requiring more bolt movement.

It is what it is and you either use it and like it or you don't. Same goes for push feeds.
