you'd need a gun that took either a stripper clip or magazines. The two magazines would need to hold 8 rounds. 100 rounds of ammo as you'd shoot 88. A rear sight capable of adjusting from 200 yards to 600 yards, a good sling that would fit around your bicep and a spotting scope. You might be able to partner up with a fellow shooter and use theirs. And ear and eye protection. I understand chamber flags are used now. You wouldn't need a shooting mat as you could lay in the dirt.
Another way is find a new shooter match if those still exist. You'd use a club rifle and DCM ammo (if that still exists).
I favored a bolt action. You could always use an AR platform rifle and a lot of the issues are solved like magazines, rear sights and how to hook the sling up. Ammo's cheap that way.
