Semi-automatic Versus Bolt-action
I figured since I did a revolver versus semi-automatic pistol entry I'd do a semi-automatic versus bolt-action sniper rifle entry out of sheer boredom. Still waiting for suggestions and input by the way...
Semi-automatic Rifle Pros.
The mosty obvious is the ability to fire consecutive shots more quickly and the ability to, generally, hold more rounds per magazine and quick reloading. A small amount of the recoil is also disspated because of the energy put into the action to chamber the next round.
Semi-automatic Rifle Cons.
The automatic ejection of a shell casing can draw more attention to the shooter than he would want. With a bolt-action he can take out the shell casing by hand rather than letting it fly out on its own. Semi-autos are also heavier and have more moving parts, meaning more things that can go wrong.
Bolt-action Rifle Pros.
There's a higher inherent accuracy because of the more solid design and lock-up of the action. And shots are more consistent from bullet to bullet, which is what a sniper generally wants.
Bolt-action Rifle Cons.
Of course one must work the bolt back and forth between shots, meaning slower consecutive firing.
Which is better? Well that really depends on the application and distance. From a very long range the superior accuracy of the bolt-action would be better, but closer up if one needed faster consecutive shots a semi-automatic would be better. But that's not to say one couldn't make a very long shot with a semi-auto or take several targets up close with a bolt-action, but they're specialized tools that each have their own niche.
