I've had at least one rifle chambered in 284 WIN for over 40 years. It seems to me that the 284 WIN's 2.17", or 55mm, is a little long for Remington short actions due to magazine COAL limits. Most people think of the 284 WIN as primarily a short action cartridge despite its case length, while few people would ever think of the 6.5x55 as being a short action cartridge because of its case length. Same case length, same COAL issues in Remington short actions, very different perspectives.
I went down the 284 based wildcat rabbit hole some years back and did them in 6-284, 25-284, 6.5-284, 30-284, 338-284, 35-284, and 44-284. Some worked better than others for me, so I've kept some of the rifles chambered in 6-284, 25-284, 6.5-284, and 338-284. I screwed the barrels off the others and used the actions for other projects.
Different folk, different strokes, but I've come to the conclusion that for the guy who wants a short action 0.284" bore rifle, the 7mm-08 fits in Remington short actions without the same COAL issues that you're likely to run into with the 284.
