Pretty much except at extended distances.
Snozz, let this riddle you no more.
The way that gas-operated semiautomatic firearms work is this. When the firing pin hits the primer, the powder starts to burn. This emits pressure as gas wishes to expand behind the bullet, causing it [the bullet] to be pushed through the barrel. In a gas-operated semiautomatic firearm, some of that gas is siphoned, in a variety of ways depending on the firearm in question, to push the bolt back, eject the spent round, and load the next one in. Bolt-actions do not have to worry about that, that is what the free hand of the operator is for. They can utilize all of the gas to push the bullet out at a faster speed. You have to 'lead' the target more with the G43 sniper than with the Mauser high turret is simply because the K98's round is traveling quicker to the target.
