After 1987,the Conservative government were nervous about issuing silencers,onto full-bore rifles,because of the carnage that Micheal Ryan caused with his AK47 in Hungerford and thought 'crazy sniper',will shoot at people silently and thus refused to believe that they were essential.However rimfire silencers were easier to get,strangely.These bizarre paranoid views also featured,short-barrelled shotguns and same calibre pistols.
But in the 90s,when the health and safety guidelines were changed,silencers were issued to full-bore guns,because hunters hunting in open,woodland areas needed to:
Be able to hunt,with out spooking their quarry and being able to hear them at the same time-so ear muffs were out of the question.
An unsilenced gun can cause distress to animals and to people that are near the area,in which hunting activities are in operation,so it makes sense to have silenced guns.
Target-shooters can't get a silencer for a gun and can't use a silencer on a bullet gun,unless it is on a zeroing range,at a Home Office approved club and that that the user,is a hunter or pest controller.
