Why do snipers still use bolt action rifles? Wouldn't a semi-automatic be a lot quicker to use?
They are more accurate at longer ranges
>>29449179
For what raisin?
>>29449184
Semi auto use some of the force of the bullet going off to push the action back therefore decreasing it's range. Also have a bolt forces you to take your time lining up a shot
>>29449246
NO. NO.
It's because bolties have less moving parts and have far more consistent lock up
>>29449246
>>29449254
I'm confused now but thanks for the replies
>>29449246
Wrong negro. Fewer moving parts, lighter weight, and a simpler design reduces the number of variables that negatively affect accuracy.

Bolt-action rifles can have a more powerful mainspring since you cock it by hand. A stronger spring adds extra bullet speed leading to a flatter shot over long distances.
Because the little gnomes that cycle the rounds into the chamber in the semi sometimes are feeling lazy and don't chamber the round the exact same each time.
The bolt action doesn't use any gnomes.

Back in the day used to be that simpler action of the boltgun would provide a consistent advantage over the automatic feeding of semi's and their multitude of moving parts. Snipers hardly need the fire rate on extreme distances and DMR's are a thing for other situations.
Could have sworn I had a picture of comparing the two before. Oh well, have this tiger instead.
>>29449461
And what I meant by back in the day is, you could probably manufacture an automatic nowadays that makes this difference negligible.

What if he misses?
7.62x54r Nugget: can hit things at 1000 yards
7.62x54 VEPR: can miss the broad side of a barn at 600 yards

>>29449254
It's both of these things.
Semi autos have a very slightly lower velocity, which technically would lower the range at which the bullet returns to subsonic speed (this is typically the point at which long range accuracy is no longer reliable, as the process introduces instability into the projectile). This reduction in velocity is not considered significant.
Semi-autos also have many moving parts which interact with each other differently from shot to shot, causing inconsistencies which reduce accuracy. In an AR-10 for example, the bolt wobbles in the bolt carrier, the bolt carrier bounces inside the receiver, the magazine jiggles in the magwell, the bolt lugs rattle in the barrel extension, the buffer rotates in the receiver extension and several other things. None of this happens in a bolt action, so those are more consistent. The very best semi autos will achieve 1/2 to 1 MOA consistently. The very best bolt actions will achieve less than 1/2 MOA consistently.
Here's an example of an exceptional semi-auto.

This. Its pure phisics! Everything else makes no sense.

>More reliable, important for guys who could be set up for days at a time for a single shot and need it to do what it's supposed to do every time
>more accurate due to less moving parts, higher precision, and better seal for the firing chamber that the bolt provides
>Single shot helps mentally force the shooter to be more accurate
>Cheaper so you can take all that money that would be spent in making a semi auto into a more reliable and high quality bolt action

YOU PUT SIGHT OF CAPTIALIST MID WEST TO SHOW OFF TO GALLON HAT COWBOY BUT STILL NOT HIT LARGE SIDE OF BARN
In a world where a drone can post a Brimstone missile through Johnny Badguy's letterbox, why even bother with sniper rifles?
>>29449997
Like most things that military does
>it's cheaper
Plus the sniper can't miss and accidentally kill 50 civilians next door to the target

Snipers don't just shoot, they watch and gather intelligence on enemy movement and numbers.

Most expensive bolt guns have free floating barrels, so the harmonics of the barrel are repeatable.
Semi-automatic rifles need some way to lock the breech, either through a reciprocating barrel, gas port in the barrel, delayed blowback which is inconstant, or an absurdly heavy bolt for straight blowback.
Any of those can screw up the harmonics of the barrel or overall consistency. I would say the most consistent of those methods is a reciprocating barrel, but it still not as good as a true free floating barrel on a manually operated gun.

Can't drones do that too? An aerial view with thermal imaging has to be better than a man in a bush with some binoculars.
I wonder if there's any point in fitting an accurized ma deuce to a small drone and using it as a flying sniper...
>>29450087
we are still a long way off from drones replacing HUMINT.
>>29450034
...which are all things a drone can do.
>>29450016 has the right idea here

Are you stupid or have you just played too much cod?
Thermal imaging just shows you theres a person there. Itd be damn near impossible to recognize anything more than the guy has a beard or maybe has a gun in his hand. If its daytime, yes, they might have a camera good enough to see his face, but when you're viewing the guy from 5,000 feet up how often do you think he's looking up where you can get a nice clean ID on him?
Not to mention a sniper can stay in one area and wait for days at a time, and can get a much more positive ID thanks to powerful telescopes and sights, and most importantly, isn't a few thousand feet up in the air bobbing around in turbulence flying at a 100mph trying to line up a shot.
Sticking a ma deuce to a drone for aerial sniping would be the most retarded idea ever considering its more expensive, easily detected if it wants to fly in range of its target, and would have to calculate leads that most snipers can't even imagine. It also has less time on target, harder time ID'ing its target, and a mount that would allow a fucking 50. Cal to rotate and target things with that much precision would be very large and complex. THEN count the delay for the controls as odds are your pilot could be hundreds of miles away flying this thing, making it like trying to snipe in a video game with 500 ping. Its literally worse than a normal sniper in every way to any person with a shred of common sense.
Now, sticking a few .50 cals on a drone and using it in a close air support fighter bomber type role by strafing targets? That could be a decent idea, but don't even imagine it be capable of anything more accurate than that.

Maybe if you're a huge scrub.

How does harmonics affect the barrel and accuracy?

Bolt rifles are naturally lighter.
Most semi auto rifles do not have the natural recoil management as an actual bolt rifle. Primarily because of the gas systems, how they operate and how they throw around weight during the shot and moment of ejection. Most people forget that the bullet is still in the barrel the moment the gas system is activated to extract the case.
>Less moving parts, less recoil management needed, less weight.
That would mean that if you had a bolt rifle weigh the same as a semiautomatic, it would most likely mean that the bolt rifle has a heavier barrel for recoil management.
>>29457023
the end of the barrel could be pointing in the wrong direction as the bullet passes it
