Push the bullet forward until it stops against the lands, lock the gauge and measure with a bullet comparator to read a true base-to-ogive length. A few thousandths of change in jump can be the difference between average and very good groups. Fits both the straight and curved OAL gauges.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Hornady\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem number:\u003c\/strong\u003e B300R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCartridge:\u003c\/strong\u003e 300 Rem SA Ultra Mag\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Hornady Lock-N-Load OAL gauge, straight and curved\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Hornady","offers":[{"title":"Default Title","offer_id":54537119400220,"sku":"HB300R","price":19.57,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0722\/0835\/1516\/files\/placeholder-hornady_5b90d3a8-ffd4-4741-8096-04e61f763149.jpg?v=1789383225","url":"https:\/\/www.magnumsports.com.au\/products\/hornady-mod-case-300-rem-sa-ultra-mag","provider":"Magnum Sports","version":"1.0","type":"link"}
