Muzzleloading deer stalking UK [except for Scotland]

[tacfoley]

Many ML rifle users actually use bullets not just ball; nothing to stop you firing a recognised expanding bullet in a muzzle loader.

As a frequent BP shooter in the USA I'm well aware of the types and style of projectiles in common use over there and in Canada, but my question is specifically aimed at shooting here in UK. Here we have a large and thriving gun club of well over 400 members, not one of whom shoots a BP rifle at a deer of any kind.

Given the total lack of interest there, my question was aimed at trying find out what there might be by way of opposition to this kind of shooting. Of course, historically-speaking, prior to the invention of the metallic cartridge, ALL deer-stalking in the UK, and everywhere else, was carried out using a muzzleloading rifle of some kind. All I'm trying to figure out for Andy, who still does his deer hinting - and everything else - with a muzzleloading rifle of one size or another - is why it is not still commonplace here in UK.c v As I mentioned in post #1 - .50cal ball weighs in at 200gr and at 1850fps makes just over 2060 ft lbs. THAT figure comfortably exceeds the 1500 ft lb minimum here in UK, apart from Scotland, where the deer apparently wear some kind of body armour.

Other civilised nations in Europe allow ML rifles to be used against game. In Hungary there is even a specific short season where, as in USA and Canada, only 'ancient/vintage' firearms of any kind are permitted - see capandball's excellent and evocative movie on that very subject on Youtube.
