Yeah, we all know- or should be acutely aware- RIFs can be banned this quickly with no act of parliament either.
I do- or did, I'm looking for somewhere closer- HEMA fencing, (smashing each other with blunt steel swords) and there's also consultation on banning those but it's not as far along as the crossbow thing, although the crossbow ban went from 0-getting outright banned with very little notice.
No idea how long it will now take for them to implement this.
I feel for the retailers as well, especially when they are quite likely to still have the loss of the blank firers still raw.
I have my eye on a couple of traditional archery bows, I nearly bought one last month, but I'm not going to bother now, don't trust them not to go further.
