PMC lists these identifiers on its X-TAC product pages. This is not a live inventory table. Confirm each retailer's package count; a retailer case label is not necessarily a manufacturer load identifier.
About PMC X-TAC M193
PMC identifies 5.56X as a 55gr full metal jacket boat-tail load. Its published velocity depends on the stated test-barrel length. That figure does not guarantee velocity, accuracy, or function in another firearm. Follow the firearm manufacturer's chambering and ammunition guidance. A .223/5.56 search grouping is not a compatibility statement.
Box vs bulk — how the packaging sizes compare
Retailers may list boxes, battle packs, or assembled cases. Calculate each listing's ammunition cost per round from its stated price and total round count. Package size alone establishes neither savings nor free shipping.
How It Compares
M193-style and M855-style listings identify different loads. Confirm the actual manufacturer identifier, bullet construction, and quantity rather than treating their names as interchangeable. Range permission depends on that range's rules, not on a general statement about FMJ ammunition.
Comparing listings
Compare current listing prices for the same load and quantity. Include known shipping costs and applicable taxes before comparing delivered totals. If shipping is unknown, an ammunition-only comparison does not establish the cheapest delivered listing. Check retailer stock and destination restrictions directly. Price alerts report observed changes; they do not identify a purchase time.
