In a quest to find out which makes a better barrier to the wrecking ball that is the .50 cal, Royal Nonesuch grabbed a few buckets of sand and water for some backyard comparison tests.
Using an RN-50 (what else did you expect?) and a chronograph to lend some legitimacy (wait, is this really RN?) the test is on. He even used ear-pro, though no eyes.
Keep it up, Royal.
