The majority opinion seems to be in favor of bolt action for snipers, and a heavy barreled version of the primary assault weapon equipped with scope or advanced sights for designated marksman.
Might be a factor in favor of bolt action.
Bigbro RE:Semi auto vs bolt action, sniper/dm weapon 6/21/2004 8:23:45 PM I think that you will find that in order to get a semi-auto to shoot as well as a well-tuned bolt gun you are going to have a lot of minimum tolerances in the chamber, bolt ect.

  Shooting Times Magazine: Your Best Bolt Action
As the cartridge is withdrawn from the action, the mouth of the case drags on the barrel and receiver ring until it is flipped out the ejection port.
In fact, the ejector is not even in contact with the cartridge case until the bolt is pulled to the rear and the ejector extends past the boltface to flip the case out of the action.
The result is that the bolt is pulled clear out of the action when the action is opened.

The action spring attaches from a screw protruding from the top of the receiver to the operating rod of the bolt.
Secondarily the action spring maintains a forward force on the bolt to keep the shell sealed against the bolt face and the barrel.
The operating rod protrudes from the top of the bolt and is the point at which the action spring attaches to the bolt.

 Types of Operation   (Site not responding. Last check: 2007-11-06)
May be 'turnbolt' in which the bolt is pushed forward and then turned down to lock by means of a handle; or a 'straight pull bolt' in which the manual action is a simple and reciprocating movement and the bolt is turned and locked by cam or wedge action.
Because bolt actions were largely developed as military arms, older rifles (pre-WWII) were usually loaded using "stripper clips" or "chargers," which are sheet metal devices that hold a number of cartridges together, usually five rounds.
The bolt is opened as the lever is pushed in a sweeping arc, forward and away from the rifle.

First bolt action rifles appeared somewhere in the mid-XIX century, and first magazine fed bolt actions were adopted by the Swiss army in the 1870s in the form of the Vetterly-Vitaly rifle.
Bolt action rifle is a weapon, which requires a manual operation to reload a weapon prior to each shot.
Term "bolt action" comes from the "bolt" - a part of the weapon that is used to feed cartridges into the chamber and to lock the barrel upon the fire.

 Ruger Bolt Action Rifles
Bolt Action rifles are among the most positive operating and accurate rifles made.
Similar in operation to a door bolt, bolt action rifles are operated by lifting up and pulling back the bolt handle to eject a chambered cartridge, and then pushing the bolt handle forward, lowering the bolt handle to lock a new cartridge into the chamber for firing.
Ruger M77® Mark II centerfire bolt action rifles are chambered for the more powerful cartridges, and are used for anything from small game and varmint hunting to Cape buffalo and elephants.

 Finest Bolt Action Rifles Ever Produced
The split rear receiver helps to prevent bolt wobble when the action is opened, but was to cause trouble later, when the use of telescopic sights became widespread, as it prevents the use of conventional scope mounts on top of the receiver.
Because the fat Weatherby Mark V bolt is so smooth in operation and has a short rotation to unlock and lock, it is one of the fastest of all bolt actions for follow-up shots.
From the Mark V action the Vanguard action derives its three gas escape vents in the side of the bolt body and a streamlined steel bolt shroud that completely encloses the rear of the bolt.

This meant the length of pull of the stock (distance from the butt plate to the trigger) had to be a reasonable length, usually around 13 inches.
A hole for the charging handle was drilled normal to the axis of motion and as close to the bottom of the bolt as possible.
The carbon rod is strong but the concentration of stress at the point where the rod exits the bolt tended to split the fibers of the rod and it would ultimately fail after 20-30 cycles.

 Some Famous Bolt-Action Rifles of WWI and WWII   (Site not responding. Last check: 2007-11-06)
The British Lee-Enfield SMLE used a cock on closing action, which, together with the location of the bolt locking lugs toward the rear of the bolt instead of toward the front, made this rifle very effective in rapid fire.
In the German models of the 1898 mauser, cocking takes place primarily on opening when the bolt handle is raised, with the last 1/3 taking place on closing when the bolt handle is rotated to the locked position and the sear engages the cocking piece.
Closing the bolt is made easier by cam-shaped approches to the locking lug recesses in the receiver ring and a slight bevelling of the locking lug corners.

 Browning A-Bolt Mountain Ti
In those days Browning bolt guns were built in Belgium by Fabrique Nationale, and two basic actions were used: the FN Mauser for long cartridges and the Sako action for cartridges of medium and short lengths.
The bolt release is on the left side of the receiver bridge; the barrel screws into a hardened-steel insert inside the titanium receiver.
Another nifty idea the A-Bolt borrows from the BBR is scissors-style follower struts (in lieu of the more common leaf-spring-powered follower), which discourage the nose of a cartridge from tipping downward in the magazine box as the bolt pushes it toward the chamber.

The next step was to drill the firing pin hole in the Bolt, which sounds easy but it has to be off centered, a stepped hole, and drilled from both side of the Bolt.
In the first picture I have the bolt centered in a 4 jaw chuck and I have applied layout dye to the face and sides, I then used a fired shell case and the TLAR method to mark the location of where the firing pin will be.
In the Second picture the Bolt has been offset using 2 of the fingers of the chuck to about.208" to allow the firing pin hole to line up with the rim.

 HKPRO:  Guide to HK Locking Pieces
This interlocking metal “puzzle” is a smooth working machine, and the two round rollers in the bolt head, and their relationship to the angles on the forward slopes of the locking piece and those within the barrel extension are the key to the whole HK system.
Bolt lug failure is uncommon in most bolt-action designs, as the locking lugs are robust, and lock up to the solid metal of the receiver.
Since the bolt head is forward to the extent of its travel, and the locking piece is attached to the bolt carrier, the locking piece is driven forward inside the bolt head.

 Bolt Action vs Double
With a bolt actioned rifle, the possibility of it choking up after the first round has been fired has to be acknowledged.
I have seen supremely reliable bolt actions hopelessly snarled up when the shooter was put under a bit of stress during shooting exercises, and it is during charges or other such emergencies that the fumbling, short-stroking and other such gremlins may pop up.
The breech locking of a double rifle is not nearly as strong as that of a turnbolt, and the action of a double"flexes" upon firing.

The Rover 870 is designed for a plethora of cartridges; the barrel length depends upon the caliber, with most calibers using a 22-inch barrel, while magnum chamberings and the.25-06 Remington use a 24-inch barrel.

The action is both glued and screwed to this sub-chassis.
The barrel is SS and there are few variants of the rifle, a heavy bull barrel (newest), an anti-terrorist model (long barrel, no iron sight, a muzzle break), the regular L96A1 (iron sight, hence front post, no muzzle break, in 308).
This example is in the sniper configuration with the PU scope and the turned down bolt handle and is dated 1944 on the receiver.

Next using a 3/16 end mill I cut a flat surface on the side of the Bolt to drill for the Extractor pin.
I then drilled completely through the bolt so the pin could be driven out if the extractor breaks.
When the Bolt is drawn back to the rear most position the firing pin will hit the receiver tube end cap and this will be enough to knock the round from the extractor and it then can be dumped from the receiver.

Three different locking lug setups are Weatherby’s bolt with nine small locking lugs in three banks of three (L), Remington’s Model 700 bolt with two opposing lugs (C), and Browning’s A-Bolt with three locking lugs (R).
A shop owner might not want you working the bolts on new guns just for testing, but there should be no problem in working the bolts of used guns.
If this is an issue for you, the answer is to purchase only an action, then have the lugs lapped by a good gunsmith before fitting and chambering a new barrel.
