Now, slide the gas seal O-ring over the barrel and tighten up against the 16mm ‘tightener’ and place the main body of the moderator over the barrel and screw onto the end cap. It is best to lightly oil the threads in this system, to aid in disassembly for future cleaning.
If your barrel is smaller than 16mm, then you can use one of the adaptor sleeves that is inserted over the barrel before the end cap. Just check when tightening this assembly that the barrel adaptor does not slip out of position. Also, if the barrel finish is a bright blue and polished, the adaptor may slip if not fitted correctly; so, I totally de -greased the adaptor and barrel where fitment would be with KG 5 degreaser and the spring steel collet did not move at all in my tests with any of the loads.
On a typical 410 barrel, here I used a 14mm adaptor on a Webley and Scott 410 bolt action and the Hushpower will sit, if probably fitted, only 7.5-inches or so in front of the muzzle and so does not affect handling or overall weight very much at all, surprisingly. You can also use the Hushpower with any 410 and in any choke and also with standard velocity rounds but best sound reduction is with subsonic rounds, obviously. However, most subs are 3-inch length, so check your shotgun’s chamber first.
It’s a very handy bit of kit, being easily adapted for use on any suitable 410 single barrelled guns.
I fancy having a spare barrel from a Remington Sporting 410 semi-auto adapted with the front part of the rib removed for the Hushpower to fit and this would make a superb, fast-handling and shooting silenced 410 for squirrels.
I like the 410 and so have a lot of differing ammunition types to test, both standard velocity and subs. The Webley and Scott bolt action 410 gun had a full choke and patterns were tested at 25-yards. The only problem was that these old Webleys are only 2.5-inch chambered, so that precluded the use of my normal 3-inch magnum and 3-inch subsonic loads. I will sort another article with a 3-inch chambered gun in the near future; shame. It’s also always worth testing each load, as even if the shot weight is more, the shot hardness velocity, closure, wadding and choke all play apart in the overall performance of any load.
Eley Four Ten ammunition is a 2-inch case or 50mm, with a muzzle velocity of about 1250-1300fps in a plastic case with a rolled top closure.
A fibre wad propels only 9-grams of No. 6 shot and, at 25-yards, I had 71 pellets hit the pattern board, with 26 within the 15-inch inner circle. No recoil and very good muted recoil, an ideal rat in the barn load.
The Eley Fourlong is bigger at 65mm case length, 2½-inches with a payload of 12.5-grams with a fibre wad and No. 6 shot size. I had 99 pellets on the board, with 38 pellets evenly distributed within the 15-inch inner circle, so plenty dense enough. You still get a supersonic crack, as the pellets are travelling above the speed of sound but it’s very small and has no lasting echo, so the moderator is working very well.
Lyalvale Express 2-inch another dinky 410 cartridge; this time, a fibre wadded 50mm case loaded with a modest 9-grams of No. 6 shot and quite a low velocity; so, almost subsonic in use. I had 77 pellets on the 30-inch pattern board, with 23 hits within the inner 15-inch circle; another nice close-range feral or ratter.
Lyalvale Express Supreme Game Here, the 2.5-inch case is ideal and has a useful 14-grams of No. 6 shot. This was quieter than the smaller payloads of other cartridges, as the larger payload is traveling slower and this shot very quietly, hovering at the subsonic level in the Webley. It also shot really good patterns but slightly wider, of 104 pellet strikes and 38 even inner strikes, for a good overall coverage.
Gamebore 2-inch Hunting I had some older 2-inch cased loads that only holds 9-grams of either No. 6 but these had a plastic wad, which helps with tighter patterns down range. This was reflected in 81 pellets in total within 30-inches, of which 32 pellets were in in 15-inches. A slight crack to it this one, as light load, higher velocity with the same powder load but still really quiet, compared to not having the Hushpower fitted.
Gamebore Traditional Hunting is a 65mm case size that uses 11-grams of either No. 6 or 7 shot, of which I had the No. 6 shot size, this being the traditional 410 shot size. I had 109 No. 6 pellets with 41 pellets in the inner sector and again the Webley’s full choke produced a very even pattern. Quit too, with a dull report from the Saddlery and Gunroom 410 Hushpower.
For the money, the 410 Hushpower is excellent value at £120 and a really handy bit of kit; I will certainly be using it on the Webley in future. It works very well, can be disassembled as necessary, or removed when you don’t need it, although I bet you keep it on. I am looking forward to testing with a 3-inch chambered gun and magnum and subs next and maybe a semi-automatic conversion. You need to check it keeps tight, which is only a problem on shiny barrel surfaces but other than that, whether you shoot standard or subsonic 410 ammunition, you and your neighbours will benefit from the sound reduction, although the vermin might not thank you.
