This \u003cstrong\u003e\u003cspan style=\"background-color: #ffff00;\"\u003e7mm \/ .284\u003c\/span\u003e\u003c\/strong\u003e bullet weighs \u003cstrong\u003e140 grains\u003c\/strong\u003e and is built around a solid copper jacket over a copper core, with no lead core. Barnes' all-copper construction is engineered to virtually eliminate fragmentation and produce roughly \u003cstrong\u003e28% deeper penetration\u003c\/strong\u003e than conventional lead-core bullets on impact.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eMultiple precisely machined grooves cut into the bullet's bearing surface initiate reliable, controlled expansion across a wide velocity range, while the hollow point tip drives consistent, predictable upset. A cannelure on the shank lets the handloader seat the bullet firmly in the case mouth without distorting the bearing surface. The tapered boat tail base reduces drag and lifts the bullet's ballistic efficiency, helping produce a flatter trajectory and better retained energy downrange.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eFor handloading, this TSX BT lists a ballistic coefficient of \u003cstrong\u003e.394\u003c\/strong\u003e and a sectional density of \u003cstrong\u003e.248\u003c\/strong\u003e, with an overall length of \u003cstrong\u003e1.265\"\u003c\/strong\u003e. Sized for any 7mm case neck (0.284\" bullet diameter), it is recommended for hunting applications. Barnes provides published load data for this projectile in 7mm Remington Magnum, making it a proven choice for handloaders building hunting ammunition. Each box contains \u003cstrong\u003e50 projectiles\u003c\/strong\u003e, ready to load.\u003c\/span\u003e\u003c\/p\u003e","brand":"Barnes Bullets","offers":[{"title":"Default Title","offer_id":54991010103618,"sku":"19870","price":42.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/7921\/5682\/files\/hires_7842b463-c5e2-45a1-8d7d-c98ed436db40.png?v=1784199100","url":"https:\/\/centerfiresystems.com\/products\/barnes-bullets-tsx-7mm-284-140gr-boat-tail-reloading-bullets-50-box","provider":"Centerfire Systems","version":"1.0","type":"link"}
