Your guess is as good as anyone's here. There were several types of rifles made for the 7.82x57 (aka, 8mm Mauser) cartridge, these rifles were manufactured by several different arsenals, and the serial number does nothing to indicate the purpose. Yours might not even be a military rifle - your question gives us no indication of the manufacturer or model - for all we know.
The Mauser es340b was a single shot .22 long rifle. It was made too look and feel like a Mauser 98K. It is not a sniper rifle. It is a target rifle.
