You didn't say suppressor, you said silencer..
Sure, I misue the term too, but you asked what hunting rifles can be silenced. Well they all can be silenced if you use subsonic ammo and a big enough silencer, but since it is impractical to carry a four foot long silencer into the woods, one must do with a suppressor that reduces the sound to within safety levels.
All rifles, shotguns and handguns can be suppressed.
When you go into the woods you can hear the numnuts out there firing and would know to stay away from that area, and probably hike out in the opposite direction of the gunshots. It's nice to know where the dumbasses are.. NOW explain to all the good people here what you have to go through to own the hunting rifle in these "relaxed gun law countries", how many classes you have to take, how much money you have to spend to GO hunting, and what other requirements are in place for someone to go hunting "alone".. Personally I'd say let them have THEIR silencers, let me keep my guns!!
To own a shotgun in the UK you need a shotgun certificate which does not require a class, but it does require a background check, a visit with a doctor, a visit to the home, and a statment for the reason to own one. Hunting, pest control and skeet shooting are reasons.
As long as they are accepted shotguns (e.g. holds less than three rounds), once one has a certificate there is no limit on the number of shotguns that can be owned and no restrictions on the amount of shotgun ammo that can be possessed. You or I can get a shotgun certificate if we resided there as American citizens.
To own other shotguns (e.g. semi auto), shot firing handguns, muzzloading revolvers or high powered rifles one must show good reason such as hunting, pest control, or target shooting. I think one mus be a member of a target shooting association if they use target shooting as a good reason. The process is a little more strict, but I don't think you need lessons here either.
I think UK's laws are ridiculous and should never even be considered here, but if a country that has very little trust of their citizens and only begrudgingly lets them have any firearms lets their citizens freely hunt with silencers and freely own them, then what does that tell us about our prudish attitude about silencers?
No, only those people that think they should be allowed to have silencers should be REQUIRED to shoot with bow and arrow.. though I agree with Smooth.. make it a sport.. stalk and shoot using bow and arrow, now that's sport!
Try removing a groundhog, rabbit, prairy dog (out west) or nutria infestation with just a bow and arrow. Varmint hunting is the best reason for using a suppressor.
Target shooting without disturbing the neighbors is another reason to own a suppressor.
Shooting so one does not damage their own ears while hunting is a damn good reason to use a suppressor.
Using a suppressor to also help minimize recoil is another reason to use a sound suppressor.
I swear sometimes some members of the hunting community are elitists that say other people shouldn't own certain types of guns so that they can keep their hunting rifle. Some of you guys are like hunter John Kerry.
It does not look good IMO.
