轉輪步鎗好處是很簡單、很可靠，可燒不同子弹。。。。但缺点是輪瓜燃氣比較有危險性，如用手持式開鎗有机會燒到左手，同埋燥音比較難於處理。。。
Happy shooting!
用上了"靜音"設計, 應該避免了輪瓜燃氣外洩問題...
特殊縮頭.44密林彈
...堅複雜

以前要打大口徑尖頭又要射得一定程度地快，唯有用輪式，始終洲長1887唔打得尖頭，當時半自動步鎗又唔係太成熟。
啞彈處理視乎把大支輪係SA定DA，SA的話再cock鎚同普通鎗拉多野bolt差唔多，DA有佢優勢但重雞用黎狙 ...
--- 設計參數: 100m, 靜音, 快頻(免trouble 操作?), 須自留彈殼
同意。 當年要近距加大威力, 加上其他要求, 輪式絕對可算是一個選項

Knight Armament's Silent Revolver Rifle
Please Note
This item is based on a real weapon. Most of the facts offered here are based on real facts. The item was featured in an article found in the September 1992 issue of Soldier of Fortune magazine. The real company who made this weapon is Knight's Armament Co. 7790 9th St. S.W., Vero Beach, Florida, 32968 and anyone who wants a copy of the complete article should let me know and I will send it out to you. The original article includes a description of the smaller hand held version as well, but I decided to just do the "rifle" for now.
Knight Armament's Revolver Rifle
An old and little know weapon has been hitting (Pun Intended) the assassination circles. Thought you would like to know about it. Here are some facts about it as far as I have access to. This info is based on an old article about the weapon.
I quote:
"Faced with a Request For Proposal (RFP) for a relatively close range (100 meters), sound suppressed sniper weapon with the potential for rapid follow-up shots and because semiauto pistols tend to spit empty cases all over the scenery and there are some operational circumstances under which this might compromise the mission the request included the requirement that there be no empty cases to police up."
"Knight responded with a tour de force totally unique in the annals of sound suppresser history. Knight's successful response to the RFP combines special telescoped ammunition with a modified Ruger revolver to which have been attached sound suppressers. Also because of the 100 meter range Knight wanted a more stable platform. For this Knight designed the 'Revolver Rifle'."
"Starting envelope for the revolver rifle is a Ruger caliber .44 Magnum Super Redhawk revolver. The crane/cylinder assembly is essentially the same. All stainless steel components have been finished by the black-oxide process."
"The factory barrel has been replaced by a four grove, 30 caliber barrel, 10 inches in overall length, with a right hand rifling twist of one turn in 9 inches. The front cylinder gap is adjusted to a maximum of 0.005 inch and a minimum of 0.003 inch."
"This is an exceptionally fast twist for a bullet weighing only 145 grains. However, the muzzle velocity is only 1,025 fps. The twist is required to stabilize the flight path of such a light weight projectile moving at such a reduced velocity, and to provide the necessary accuracy potential. To further minimize the tendency of the slow moving projectile to yaw in flight, "driving" or "rotating" bands have been milled into the flat based solid brass bullet in the manner of many artillery shells."
"Screw-turned with a needle sharp point, the bullet is encased in an aluminum piston with a black plastic front face seal. Both are loaded into a Federal .44 magnum case. Powered by an undisclosed propellant of undisclosed charge weight and upon ignition, the piston moves forward a small amount and its beveled face interfaces with the rear end of the barrel to seal the front cylinder gap. A rubber O-ring on the piston seals the case from propellant blow by, so that all of the propellant gas is driven into the sound suppresser attached to the barrel".
"An unusually long sound suppresser (18.5 inches) fits over the barrel and is attached to the revolver by means of a knurled, threaded coupler on the front end of the frame. The suppresser's housing is made from black-anodized, 6061 T6 aluminum tubing. The interior consists of a series of steel and aluminum baffles, together with rolled metal screen material. This suppresser has an exceptional life span of 5,000 rounds or more."
"The sound signature produced by this system is about 119 dB. The sound pressure generated buy the weapon unsuppressed is about 163 dB. The sound of the hammer dropping on an empty chamber is about 112 dB, so the muzzle blast is reduced to only 7 dB more then the sound of the action and the firearms flash signature is completely eliminated."
"The black polyurethane forearm under the barrel has a quick release stud to which a Harris Bipod can be attached. A detachable polyurethane and steel buttstock is also provided. The overall length of the Revolver Rifle is 36.5 inches with the buttstock and sound suppresser attached. Weight is about 8.5 pounds."
"The standard type, open notch rear sight has been let in place with two horizontal tritium bars. A single tritium dot has been installed on the serrated blade type front sight mounted on the front of the suppresser housing."
"What's the accuracy potential of these esoteric snuffers? The weapon was tested at 100 meters from a bench rest. 2 inch groups were fired until it became monotonous. That's more then sufficient to meet any Mission Essential Need Statement likely to have been developed for this weapon system. Without a doubt, C. Reed Knight Jr. has created a most impressive and totally unique weapons system."
End Quote.
