I spotted this rifle over at longrangehunting.com. Is it anti-air artillery or a deer rifle?
Built by a New Zealander … they sure know how to build a cool rifle.

Beautiful scenery
The rifle has a custom suppressor with a muzzle break! Here is a close up:
I assume the “404″ refers to the 404 Jeffries.
my suppressed 7mm/404 which weighs 20 pounds all up, and pushes a 180 grain Berger at 3350 fps.
Wodger Wabit over at RFC machined a suppressor adapter for a Volquartsen carbon-fibre wrapped barrel threaded for a .22 muzzle break so that both can be used. Neither the suppressor nor the muzzle break need to be modified. Very cool.

Adapter screwed in, ready for the suppressor.
UPDATE:
The creator of the adapter, Roger, just sent me an email. Check out his website. It contains lots of interesting information on suppressors and air gun hunting.
These tests were conducted on January 5, 2008 using 19 silencers from various manufacturers around the country. Some of the best silencers in the world were measured in this test. The test was fired using the Walther P22 pistol and a bolt action rifle manufactured in Russia call the Tula Toz 78. This is the preliminary release of this data and more individual reviews will become available as time permits.
Unfortunately, they require you to register (for free) to view the info and the videos are normal windows video files, not hosted on youtube type sites. They really need to get into this blogging ‘thing’.
What is interesting is that the second best suppressor, with regards to noise reduction, costs $295.00 while the worst costs $595.00! I have always said I do not trust these ‘high tech’ expensive suppressors.
How far would you go to enjoy 12 gauge shot gunning without disturbing the neighbors?
Wendell Diller has invented a lightweight shotgun barrel extension that is about 5 feet long!
When Sean Coffey’s honker call pulled a flock of geese within range, paraplegic Dave Guzzi swung his shotgun with a 7-foot-long barrel and dropped one of the geese dead.
There was a moment of stunned silence — and not after the goose tumbled out of sky. The morning stillness was barely disturbed when Guzzi pulled the trigger on his extraordinarily long shotgun.
The sharp blast of the 12-gauge was replaced by a muffled fzzzttt. Sitting just four feet away, I was struck by how the shotgun sounded like a loud air rifle. Guzzi, who lives in Burnsville, laid the experimental shotgun between his legs and waited for more geese.
“Pretty amazing, isn’t it?” he said of his gun.
Apparently it is also useful for deer hunting.

This video from SHOT Show 2007 shows Advanced Armament’s new suppressors. Including a quick release suppressor designed for the SCAR-L, the quietest .45 pistol suppressor (or so they claim), a new AR-15 and .22 suppressor.
a class three dealer examined it and said in his opinion it could not be removed and attached to a firearm with success.
Gamo has taken pains to make the outer case tapered front-to-rear, plus they have molded two huge flutes into the side of the case. They’ve also made holes in the flutes that expose the sides of the baffles, which are a soft synthetic material, to the air.
It was his opinion that the silencer would be too difficult to remove from the rifle without destroying it, and, even if it could be removed, that the baffles would blow out the sides if exposed to even the low pressure from a .22 rimfire cartridge. In other words, it wouldn’t silence a firearm for even one shot.
B.B. Pelletier reviews the Gamo Whisper, Gamo’s suppressed air rifle which I blogged about recently.
Noise is what the new Gamo Whisper is all about, and I’ll address that issue for you right now. I don’t find the Whisper to be that much quieter than any other spring piston air rifle of comparable power. In fact, my tuned .22-caliber Beeman R1, which has no silencer, is quieter because its powerplant makes less noise. The powerplant is where the bulk of the noise of a spring gun comes from, not the discharge at the muzzle.
This article has a great comparison between wet and dry suppressors. It also includes some great videos.
The term ‘wet’ means some sort of liquid, be it oil, water, grease, gel or another substance is used to cool the gasses exiting the suppressor. The gas leaving muzzle or suppressor is what causes most of the noise.
“Wet” suppressors or “wet cans” use a small quantity of water, oil, grease or water-based wire-pulling lubricant in the expansion chambers to cool the propellant gases and reduce their volume (See ideal gas law). The coolant lasts only a few shots before it must be replenished, but while it lasts it can greatly increase the effectiveness of the suppressor. One manufacturer claims a 30% improvement in sound suppression for “four magazines” (32 to 68 rounds) with the addition of 5 ml (one teaspoon) of water or light oil to their suppressor.
I am a big fan of suppressors and own two. I have a .22LR and a .22 Hornet suppressor. My hornet suppressor can also be used on a .22LR or .22 Magnum (WMR).
In the near future I am going give ultrasound gel a try and see how it works.
Hi, welcome to my blog! This blog is dedicated to all things firearms related. I hope you enjoy it.
I want this blog to appeal to a worldwide audience and so I will be focusing on firearms and shooting rather than country specific politics. There are already many great blogs defending your rights!
