-Mongrel- Posted July 17, 2011 Report Share Posted July 17, 2011 Just a query really as I have nothing to compare it against, but how much 'internal' noise should there be from a S400 Classic? Mine makes a definte twang when it's fired, loud enough for the rabbits to be alerted to it. It fires well (chrono'd at 11.2 ft/lbs) and gives 10p groups at 35 yards, so I don't think there's much wrong with it, but I just wonder if it needs a service maybe? To be honest it's probably no louder than the 'smack' of a pellet/rabbit head interface, but it has caused a a few moments of consternation on the longer shots as the rabbits have been alerted and moved a little before pellet strike. I haven't had a non lethal strike as yet but it does cause concern to the point that I've become reticent of taking the longer shots. Any observations from other S400/410 users or airgunners in general would be appreciated. Quote Link to comment Share on other sites More sharing options...
sitsinhedges Posted July 17, 2011 Report Share Posted July 17, 2011 Mine has a bingggg sound as it is fired, just the sound of the hammer spring I think. Be nice if it was silent but I can live with it. Superb rifles Quote Link to comment Share on other sites More sharing options...
Gnome of the Woods Posted July 17, 2011 Report Share Posted July 17, 2011 All S4xx do it to some degree, you think it's loud because your head is resting on the stock and it resonates. Get a friend to fire it and stand 15yds away, the only sound you hear is the pellet zipping through the air. Quote Link to comment Share on other sites More sharing options...
Beretta28g Posted July 17, 2011 Report Share Posted July 17, 2011 Due to the internal mechanism there will be the sound of a sprung loaded hammer hitting the firing valve. Quote Link to comment Share on other sites More sharing options...
FalconFN Posted July 17, 2011 Report Share Posted July 17, 2011 It's unlikely that the sound of the hammer spring would spook rabbits at 30 yards. Test it by dry-firing it 30 yards from a rabbit and see if it does anything more than look up for a second. The reaction time for a rabbit should not be fast enough to move before a pellet strikes.

-Mongrel- Posted July 17, 2011 Author Report Share Posted July 17, 2011 Just goes to show how sensitive those long rabbit ears really are then! In all other respects I have to say it's a brilliant gun, combined with a Rowan mulishot conversion it's just about the perfect hunting airgun in my opinion. I bought the 400 rather than the 410 as I do a bit of HFT too so it makes life easier...and it was slightly cheaper, but the Rowan conversion works very well.

Gnome of the Woods Posted July 17, 2011 Report Share Posted July 17, 2011 The Rowan mags are top bits of kit, and the Rowan boys are top lads too. Like you say for ease of slipping between hunting and HFT there is nothing to beat it. Quote Link to comment Share on other sites More sharing options...
-Mongrel- Posted July 17, 2011 Author Report Share Posted July 17, 2011 (edited) It's unlikely that the sound of the hammer spring would spook rabbits at 30 yards. Test it by dry-firing it 30 yards from a rabbit and see if it does anything more than look up for a second. The reaction time for a rabbit should not be fast enough to move before a pellet strikes. I've been led to believe dry firing is a bad idea, does the internals no favours allegedly. I'd agree that it's nothing more than making a rabbit lift it's head, but how far has it's head got to lift before it becomes a non lethal strike. I've taken to only hitting longer range rabbits when they are head up, and have stopped going for 35 yard hits altogether. Edited for a typo.

Gnome of the Woods Posted July 17, 2011 Report Share Posted July 17, 2011 Dry firing a PCP is fine, it's springers you should not dry fire. Quote Link to comment Share on other sites More sharing options...

Even if you have a .22 the time for a pellet to reach the bunny will be 1/6th of a second a 30 yards, and no rabbit can register a sound and move more than a mm or two before it's dead.

Dry firing is fine for PCP Ok, cheers for the info. As for the dry firing thing, as both you and Gnome have pointed out, a little knowledge is a dangerous thing!
