It's good enough to shoot people with and that's without expanding bullets, so theoretically it should be fine for Roe!
There are some strange differences between Scottish and English deer law which would be better unified.

I'm not from the uk but I find this whole ft/lb arguement very interesting, the military are sent out to defend themselves and their country with 0.223 rem but the civilians need a 6mm or bigger to knock over a 40-50 kg deer.
i have only had the pleasure of roe hunting once and that was in Scotland ,with a 22-250 got a little Buck just under 200 yds and it flattened it. I have looked at YouTube clips of roe deer shot with various calibers and often wondered are these little deer just really tough or are hunter just getting pass through with bigger calibers . They just seem to run on after getting hit with what one would consider good kill shots.
I know bullet construction is paramount, I just sometimes think maybe we are all a bit over gunned? A lesser caliber, good technique and sound shot placement might yield better results.
