Dreamline classic cannot change calibers???

So I think what you'll find is that the brass ported end is different between the dreamline and impact. However I'm reasonably certain I've seen people change those out and run Impact length barrels on Crowns. (and the Crown and Dreamline have similar actions) There is no explicit kit which does it, to my knowledge, however I believe some hodgepodge of parts can be used to make it work. Or, of course, you could fabricate a handful of parts to make it work. *shrug* I hope that helps mate. 


*edit* 
Excuse me, I think in my haste I may have misread your original post. Your .25 caliber dreamline can be converted to .22 caliber, most certainly, I just don't believe there is a 700mm barrel for it. Here is a link:

... The Dreamline and Crown magazines are interchangeable, but I don't think the barrel are and the probes definitely aren't interchangeable.

Crown barrel is the same as Dreamline, only limiting factor is shroud

Crown is using bigger diameter shroud, it can be mounted on Dream-Tac with a skinny aluminum tank, but can't be mounted on Classic because of the shroud size, not because of the brass port, even Impact has the same brass port
