Thread: overlap between cartridges

Greetings All,
It is going to be interesting to see what happens over the next 20 years or so (especially for those that are likely to live that long). The ranks of 6, 6.5 and 7mm cartridges are already packed with .270 and .30 calibre not far behind. Efforts to introduce new .22 and .25 calibre cartridges seem to have gone nowhere. Is there room for a new .22 calibre cartridge between the .223 and the .22-250 with an intermediate capacity and fast twist that would split the difference between the two. I am not talking of a wildcat but a factory offering. It could have a little more mag and neck length to handle a longer pill and fit in the medium bolt face.
Regards Grandpamac.
