ELI5: What makes bolt action rifles more suitable than semi autos/full autos to fire more powerful ammo?

Why bolties more common for shooting large calibers?

It is simpler to make a bolt action system with high strength, ruggedness, reliability and accuracy compared to other system and the weight will be lower and they are cheaper to produce.


The disadvantage is rate of fire. But for many application like hunting, target shooting and precision shooting that is not a a huge disadvantage compare to the advantages.

Large powerful calibrates are primary used at long range where accuracy it one of the most important factor.

For man portable military systems weight is important both for the weapon and for the ammunition.

So you either have sniper rifles that can be move quite easy that are light and often bolt action to increase accuracy and reduce weight and ammunition use.


Or you have heavy machinguns that are hard to transport and use a lot of ammunition so you like to use them on vehicles where you even have heavier cannon system both smaller full automatic and larger that you load manually or some semi automatic.
