The \u003cstrong\u003eblack anodized\u003c\/strong\u003e block lets the reloader confirm that handloaded ammunition will drop freely into a spec chamber before it ever goes near a live rifle. This is the single most important safety check you can perform on a finished round.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eThis \u003cstrong\u003emulti-caliber\u003c\/strong\u003e gauge (Lyman part number \u003cstrong\u003e7833003\u003c\/strong\u003e) covers the most popular \u003cstrong\u003emodern sporting rifle\u003c\/strong\u003e cartridges in a single block, including \u003cstrong\u003e.223 Rem\/5.56x45mm NATO\u003c\/strong\u003e, \u003cstrong\u003e6.5 Grendel\u003c\/strong\u003e, \u003cstrong\u003e6.8 Rem.

Use it after every loading session, and especially when changing brass lots, bullet profiles, or dies, to catch a stuck case or an over-crimped round before it jams, cracks a case head, or damages a firing rifle.\u003c\/span\u003e\u003c\/p\u003e","brand":"Lyman","offers":[{"title":"Default Title","offer_id":55002559545666,"sku":"102213","price":45.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/7921\/5682\/files\/hires_c3143223-b330-47c6-b317-1972049561f3.png?v=1784535671","url":"https:\/\/centerfiresystems.com\/products\/lyman-msr-ammo-checker-block-multi-caliber-aluminum-black","provider":"Centerfire Systems","version":"1.0","type":"link"}
