    I just spent a hour on the search feature, but seems like all I come up with are vague opinions. Is there a situation where I need crf and/or mechanical ejection? Like will br cases not work etc? Is it a matter of smoothness? Help me out please. I plan on building a gay tiger in the next couple months and have a barrel, trigger, stock, bottom metal, and no action yet.
     
    I like mechanical ejection because you can control where the case goes.
    Send it like a boss or dribble it out the side and everything in between.

    CRF is liked by some running jam prone cartridges
     
    Do most actions that have mechanical ejection also have crf?
    It almost necessitates it. The Kelbly Atlas Tactical and Black Bear Tactical are the only ones I know of that have a push feed mechanical ejection combo. It just makes it easier to mechanically eject the round when it's being held snugly against the bolt face by the extractor. There's no chance of it popping off before it's been ejected.
     
    You won't need an extractor or an ejector with the gay tiger, it's been anointed from the heavens and God's own hand will remove it from the chamber and deposit it in your bag for you.
    Hahahaha. Man that would be nice to throw this dumb brass marker away. I bet it loads your mags for you too, and after kcshooter on ig got sub 5sd with staball, it probably loads itself too.

    What action do you recommend? Should I just go tried and true life defiance/surgeon or?

    That completely depends on your situation. Lots of people like the Bighorn TL3/Origin. I personally shoot an ARC Nucleus. There's tons of great actions out there. Curtis, Terminus, Impact, and Defiance all come to mind.

    What's your needs and wants for an action?

    To answer your original question: no, there's not really a situation in which you "need" CRF. Push feed is just another way of getting the cartridge to the chamber. As people have mentioned, some cases like the Improved BR variants (short, stubby, steep shoulders) see lower rates of struggle when used in CRF actions, but some people still see their fair share of issues. For the GT, the claim is that those feeding issues have been nullified by the case geometry. CRF or push feed should serve you well.

    So I had the opposite, I had ejection and feeding issues until I went to a crf action in my bra although my money wasn’t awesome at the time so I went with a apr hunter which turned out nice. So what I am asking I guess is a crf action smoother? Even potentially? Or does it not matter in that case?

    I disagree slightly, in that there are a few instances where CRF is "needed". It isn't needed for feeding, per se, but rather extraction of short cases. Because a CRF action retains the case against the bolt face until the mechanical ejector pushes/springs the case from the extractor, it keeps the case from inadvertently coming off the bolt face and being left lying in the action.

    It the same reason Remington had to change the timing of the ejector on their 700 rifles in 17Fireball; the case would eject off the bolt face prematurely. A CRF bolt operation negates this, since nothing is acting against the case until it hits the mechanical ejector. It's also why some of these short 6mm cases seem to function fine in the various CRF and AICS magazine based rifles. It's all about timing where and when the case goes from mag, to bolt face/chamber, to ejector.

    I always forget about that issue. This is a very valid point

    Smoother? No, I don't think there's an appreciable difference in the smoothness of an action based on CRF/PF

    “Smoothness” is more an artifact of parts aligning and mating together, rather than whether it is CRF or PF. Either can be smooth if everything is aligned correctly. Conversely, either can feel rough as shit if things are not fit well together (one of my Savage PF actions comes to mind).
     
    My nucleus is plenty smooth, my buddy’s worked 700 is as well.
    CRF and Mechanical ejection are features, not a necessity but certainly a nice option.

    When I was action shopping mechanical ejection was definitely on my wants list because I’m a brass whore.
    CRF was also somewhat wanted because I plan on a 6 BR barrel soon.

    I've been running an Origin since last november and really enjoy the mechanical ejection, like stated before you can either chuck brass like a baller' or let it dribble out into a neat little pile. Ive been running it on a 6Cheatmoor and its been awesome in a match setting since i hate playing hide and seek with brass.
