It isn't a thing of beauty, but this moderated Mossberg .410 is a brilliant tool when it comes to controlling vermin.
There always used to be a stigma attached to silenced .410 shotguns.
Anybody using one was invariably branded a poacher - especially in the days when pheasants made decent money at the local market.
Some poaching still goes on of course, but nowhere near the scale it used to be. And that's down to the price commanded by a gamebird these days: the few pence they sell for means poaching is no longer worthwhile, and certainly not worth the risk of prosecution.
Now that poaching is no longer fashionable or profitable, you would've thought the silenced .410 had become something of a rarity.
Not so. There are now more small bore guns around today with moderated barrels than ever before!
The reason for this is simple: silenced shotguns have become more acceptable in recent years thanks to the huge rise in popularity of moderated rifles for rabbit, fox and deer control.
Nobody in their right mind would want to use a .410 shotgun on deer but for vermin and rabbit control a small bore is ideal, especially when fitted with a moderator.
It doesn't take long to get accustomed to the forward-balance caused by the moderator.
One gun that's becoming increasingly popular for this type of work is the American-made Mossberg pump-action. It's soundly made, reliable and affordable.
It's distributed by York Guns and it has a Hushpower moderator, fitted by the Saddlery and Gunroom company.
In basic specification this gun comes with a 3in chamber and 24in barrel carrying cylinder choke. To enable it to be held on a shotgun certificate the magazine capacity as been restricted to two with a third cartridge in the chamber.
Bigger capacity magazines can be bought as long as you've got dispensation from your local firearms department to own one on a firearm certificate.
The pump action is both smooth and positive with the safety catch being neatly positioned on the gun's top tang. Mossberg have fitted it with a wood stock and fore-end, and treated all metal parts to a blued finish.
Everything in moderation
In the past the only way to sound moderate this model was to retro fit a Hushpower tube that fixed snugly over the end of the barrel. The disadvantage here was the process added extra length to the gun, making it unwieldy and difficult to move in confined spaces.
With this new conversion, the moderator is much longer, but it comes back over the barrel almost to the fore-end. There is a 2in increase in length to the barrel, but this is quite manageable and you soon get used to the gun's pronounced forward 'lean'.
Moderators work by dissipating sound waves from behind the shot load and this Hushpower conversion does it via a series of carefully cut holes towards the barrel's muzzle end.
These are placed at precise distances to ensure the maximum amount of noise can pass into the moderator's baffle system for dissipation before the shot exits the muzzles.
This moderated Mossberg .410 has a reliable pump-slide design.
It has to be said shotgun moderators are rarely quite as efficient as rifle moderators because a rifle only has to cope with a single projectile - not a shot load carrying wadding materials and numerous lead pellets.
Even so, this gun and system muffle the crack of a shot very efficiently. But if you really want to improve performance in the sound moderation, then Saddlery and Gunroom have loaded subsonic .410 cartridges which significantly reduce noise levels.
