I'd assume they were able to recover bullets, and you could tell if it was his gun or not that fired them based on ballistics.. so planting casings makes no sense unless the the investigators are in on it.. in which case why even bother planting casings?

Do ballistics work on hypersonic rifle rounds? They fragment and splatter into tiny shards...
