Winchester didn't make a short action until after 1964. I want to say it was into the 1980's when they first came out.
If you are asking about the CRF rifles made since the 1990's then yes all of them, long and short action feed fine. They will allow you to load directly into the chamber and the extractor will snap over the rim. Not only Ruger and Winchester, but all modern CRF rifles will do this and it is still true CRF. I've seen the rare rifle from Ruger and Winchester that may allow the cartridge to move forward 1/4" or so before the rim gets into the extractor. But it is under the extractor long before entering the chamber. It is a non issue with any of them.
The rounds coming from the magazine on any of them slide into the extractor and can be ejected without closing the bolt just like on the older guns. But there is a bevel on the extractor that will allow it to snap over. In other words it works both ways now. It has always been a fairly common practice to modify older guns to do this as well.
I've had 5 newer style 70's in 30-06, 300 WSM, and 308 as well as a Kimber in 308. I've had several CRF Rugers as well as several Interarms MK-X's over the years. All worked exactly the same, all feed perfectly.
