In comparing a bolt action to a semi-auto.
Semi-auto: Mag fed, easy to maintain, don't need match ammo
Bolt action: Like the Model 700 M40A1 you need match ammo, chambers only five rounds, and need constant cleaning.
And yes Hollywood played a big roll in calling bolt actions "sniper rilfes" but you pretty much snipe with anything. Put a scope on an M60 and put the fire selector on semi and your good. As long as you can get a long range, controled shot.
