I suppose that without much in the way of forests, bow hunting deer also isn't much of a thing in the highlands.

Bow hunting is illegal in the UK. Permitted firearms and ammunition are also regulated on animal cruelty grounds. http://www.thedeerinitiative.co.uk/uploads/guides/90.pdf

Most US states also regulate which cartridges can be used on deer, also for animal cruelty reasons. Certainly Minnesota does.
