Push Feed vs. CRF Accuracy

[Buckmastr]

I am, perhaps, having a little trouble with comprehension as I get older but I need to have someone explain how longer range makes lock time more of an issue. The fact is, lock time is an issue when firing from unsteady position and/or if the shooter's technique and follow through are flawed. As long as the shooter is able to maintain point of aim until the bullet leaves the barrel, the lock time has no real effect. To compare a Mauser to a Remington and declare the Remington shoots better because the lock time is quicker is to ignore all of the other differences between the two rifles.
More of a detriment than a longer lock time is a heavy striker fall which may disturb the rifle prior to ignition and certainly prior to the bullet exit. Even so, good technique will minimize any disturbance.
The thing is, you cannot isolate one variable and say, "this is the difference" unless that is the only variable; yet, that is what is happening here.
The type of extractor affects accuracy? Don't be ridiculous. The feeding system affects accuracy? Not likely. The rifle is a system and some parts of that system have an effect on accuracy while others do not.
Lock time is one of those things which, while everyone mostly feels quicker is better, there are compromises. In the attempt to achieve quicker lock times, some actions have done so at the exspense of reliable ignition. This can have a much greater effect on accuracy (and actually have a greater effect at longer ranges) than lock time.
Again, I have to point out, this has little to do with the original question.

The way I see it, the quicker the bullet leaves the barrel after I want it to, the better. Rest or not.
Technique? Good, bad or ok doesn’t always happen the way you want it to in a hunting scenario as you know.

Longer range magnifies mistakes.
Rimfire or high power silhouette is a good example, lock time matters. There is no downside to quick lock time.

Who wouldn’t want quicker lock time?
And cake?

NO cake BUT Quick Remmy lock time and Apple Pie for me ! RJ

Bit of a resurrection .... but in 63 posts .. no one mentioned the ejector. ‘Most’ push feed actions have spring loaded ejection plungers (Sako is one anomaly) while ‘most’ true ‘CRF’ have a standing blade ejector. When the action with a plunger style ejector is closed on a round in the chamber the ejector exerts a force on one side of the cartridge base..... while blade ejectors (which are mandatory on true CRF actions for reasons that should be apparent) exert no pressure on the chambered round as they aren’t engaged until the spent casing is being extracted. The effect of the asymmetrical pressure on the base of the chambered cartridge and ultimately, accuracy, is an interesting question and warrants thoughtful consideration

On my “target” rigs that I shoot only at the Range, I remove the ejector pin.

I think that is prudent.
Personally I believe that one of the small touches on Sako’s (and a few other rifles) that may contribute to their accuracy is the lack of a spring loaded ejector plunger.
