Like Colin I've always thought "yeah they look cool", but justifying having one, no chance, there's probably only a very select few that could tick all the potential boxes for possibly owning & using one, think wealthy landowners with massive estates, & suitable things to shoot at (legally), & i would imagine anyone who fits the bill probably already has rifles, maybe even a gamekeeper to do the dirty work.
Only other viable option is a target shooting club setup, similar to your average shooting club, where all the kit is registered & kept under lock & key, but do they exist ?, i thought most clubs used proper bows ?
BUT
I'd have preferred the authorities, irrespective of party, had given more consideration to there being a legal avenue for legitimate users, either current or future, rather than an outright ban that will just drive many of those in circulation underground, almost definitely in to the wrong hands.
