I did quite a lot of stalking in Sutherland at the top end of Scotland and never shot any particularly large or impressive animals. That was partly because the stalkers want to retain their dominant stags, so it was management stalking rather than trophy hunting. That said, my girlfriend (now wife) shot a heavy 14 point stag up there in 2010.
The roe there are truly tiny compared to the animals in the south of England.
As flyblown says, lowland reds are different animals altogether. In Norfolk there are forest reds that are huge. I was out with a mate who shot a big stag that went 180 Kg in the larder gutted and legs and head off. That bugger took hours to recover, gut and shift into the larder. I saw bigger ones than him over the years too.
