My mistake, it is push feed. Golly, now it is a 67 mustang. Still happy!
It’s neither.
It is a CRPF action. Controlled Round Push Feed.
Some would say the CRPF is the best of both worlds because though it is not as strong an extractor as the CRF claw, it DOES allow easy loading of single rounds because—much like a Remington—it can just “clip” over the rim. The rounds also do jot have to be fed from the magazine. That’s the nice bit of “Push Feed”.
IF fed from the mag, however, a CRPF does act as a Controlled Round Feed, where the rim slips upward out of the mag, and under the extractor, lining the round up with the chamber to be fed STRAIGHT in, and controlled while this happens. That’s the nice bit of “Control Feed”.
A CRPF also does these things and retains a fixed pin ejector (excellent/best), and the smoothness of an action without the large Mauser claw (which, for all its strength, is anything but elegant in one’s paw).
A true Push Only action like the Remington only has full control of the round while it’s under the feed lips, and after that, can ONLY CONTROL ONE AXIS AND DIRECTION of shell movement (forward) until control is regained by the chamber.
Short version: a Push Feed jangles the round around and relies on up being up and down being down for the action to work right.
The CRPF is well thought out, and is used in everything from rimfire rifles through what you see here.
Enjoy!
