都这么说。 可军方的sniper不是也用自动枪。 特想找一个compromise.

In the sniping community, there are basically 2 schools of thought ... the USMC philosophy is one-shot, one-kill ... and they love the M40 series (Remington M700 based sniper rifle). The USA (Army's) philosophy is maximum target acquisition, multiple kills ... and that is why (back in the Stone Ages when I was affiliated with the Army) the Army held dear to the M21 Sniping System.
Basically, the M21 is a Match Tuned M14 that is equipped with a very nice A.R.T. Scope and a very effective suppressor. The problem with the M21 system (which I trained with) is that use of the suppressor affected bullet performance (velocity) and reduced the effective range of the M21. The down side with the M21 was that you had a very fast follow-up shot waiting, so you could either be "sloppy" as you set up your shot, or you could quickly engage a subsequent target. Many of the people that I trained with knew they had a back-up round ready, and tended to burn through their ammo rather quickly.
On the flip side, the Marines have always been trained to conserve their ammunition ... many of the Marine snipers that I know rarely went out with more than 2 boxes (40 rounds) of match grade ammo for an operation! The Marines have essentially mastered the stealth and wood craft needed to become master snipers!
It basically comes down to a philosophy and a mind-set! The bolt gun is historically more "inherently" accurate than a semi auto, but they can be made to come real close! If you look at the current crop of .50BMG Sniper rifles, I think you will find more Barrett M82s out on operations than McMillan 50s! Additionally, the bolt gun is less delicate and dependent on "timing", as is a/am (semi-) auto rifle!
Additionally, you have to look at military expenditures ... the services are charged with an almost impossible task, yet the funding is not there. The Army no longer makes their own rifles, like they did prior to WWII (i.e.: Springfield and Rock Island Armories), they subcontract (i.e.: in WWII, you had: Rockola, Winchester, H&R, IHC, Smith Corona, Remington, etc). Today, the military generally has to purchase from foreign manufacturers (i.e.: the M16A2 and variants are manufactured by FN). Bottomline, they do not have control over costs. A Springfield Armory National Match M1A (basis for a clone of the M21) is well over $2000, while the USMC can purchase a Remington 700 for as little as $600. Then, the Marines have their armorers at Quantico "build" the M40 to their specifications.
When you discuss snipers, their equipment, and training, you must look first at the Military, because the police and other agencies tend to mirror the military, but work within the same constraints. Additionally, most other countries do not follow our military's philosophy on marksmanship, and do not build their equipment to meet the specifications we have imposed!
