Not really. The PF in line feed wins because of simplicity.

The calibre is also another issue. A 458 with blunt bullets has a greater need for all things to be working well.

The simple fact is a stagger feed CRF has to be "more right" than a PF with in line feed.

No.

You pick rifle or the set of anecdotes you prefer and go with that.

Actually I believe the egg came first. I normally have them for breakfast, chicken for lunch or dinner. Big Grin

Actually, inline feed with crf , fe + fbe would be the simplicity winner. Problem is , not much available for detachable mags that can handle a 458 or larger, longer rounds. One may be able to alter a 338 Lapua mag for some rounds . But the genius trust hasn't put on their thinking caps to solve that problem yet.
If mags could be made to take the recoil and other abuse of big bore rifles it would be a better system. Easy to put in a fresh clip (top off ) during a lull in the shooting/chasing.
I've never tried "lunch boxing" a fixed mag by turning the rifle over , opening the floor plate and dumping some rounds in. Maybe that would work. At least there would be a live one in the barrel. ????


Phil Shoemaker : "I went to a .30-06 on a fine old Mauser action. That worked successfully for a few years until a wounded, vindictive brown bear taught me that precise bullet placement is not always possible in thick alders, at spitting distances and when time is measured in split seconds. Lucky to come out of that lesson alive, I decided to look for a more suitable rifle."

After years of using, and liking, both PF and CRF bolt actions, I've come to the conclusion the real benefit of the CRF is NOT the feeding, but the ejection. Given two well tuned actions, one a PF and one CRF, the CRF will eject loaded rounds much, much better because of the blade ejector. There may be actions out there with PF and blade ejectors (I think the McMillan G30) that would provide the same benefit.

It's not often a shooter needs to eject a loaded round, but it sure is nice to be able to do so.

I reckon the advantage of CRF is when you are spotlight shooting. You push the bolt forward and of course turn it down for a shot but no shot and you just pull the bolt back. However, a PF requires you to close the bolt (and thus load and cock the rifle) to get the round out of the chamber.

This is always a silly and never ending argument.
Simply choose whichever you want and use it. If you never have a failure then you can claim you were right and if you do experience a failure and manage to survive, then you can try the other one.


Anyone who claims the 30-06 is ineffective has either not tried one, or is unwittingly commenting on their own marksmanship

Funny, I don't have either of those systems in my single shot.

Me neither. Sort of a push feed I guess.

True, but in the back of their minds, push feed guys will always know that CRFs are just a little bit better......and that CRF users are just a little bit smarter........

Single shots are the ultimate CRF

That's a good one, best statement on this whole thread. clap
Can we talk about the 270 WCF versus the 280 Rem next?
On the medium bore form, of course, where it will not be such a big bore.

Actually, I was going to ask for people's opinions on a two position safety vs three position safety.

Perhaps a new topic should be added under other topics titled horse where topics such as this would be moved:-)

I don't think so. This was the best discussion on the this subject I have ever read. There were many points brought up that had not occured to me. Some may call it beating a dead horse. I found it educational.

Ive seen one double and one single shot lock up when the shooter in his haste and fear closed the gun before the cartridge was fully seated, pretty damn funny !! in one case the observer had to shoot the buffalo!! that be me..The Ruger no. 1 gun on big buck second shot cut the 06 case in half, the doubler rifle shooter just squeezed both cartridges out of shape but they would not chamber...African comedy at its best..the expressions, language and screams were the best! rotflmo
