If you prefer low volume of fire have you considered a DMR platform? M14, SR-25, etc. Most fields limit DMRs to semi auto only, limit to certain models (usually based on 7.62x51 or similar) and depending on the field you may be entitled to a higher muzzle velocity.
Just that starting out as a sniper usually means wasted money/quitting the sport for newcomers. Make the sniper rifle your vanity/side project gun rather than the one you run around the woods with.
