I've been told by a 'smith that it's feasible to put together a 6,5 swede on a Winchester SHORT action as the magazine box will accomodate the cartridge.
I also agree with the 6mm/expert statement. I use a 6mm-223 for deer myself (allthough I'll make no expert claim
) and have shot 14 so far this year. My little 6mm is wonderfully effective, but every once in a while (3 so far) the deer runs leaving very little sign and blood. I know that if this had happened in my younger, more inexperienced years, it would have made for a lot of unnecessary fret and worry.
In comparison, the deer would run maybe once or twice a year when using my 6,5x55 and 120gr NBTs.
