7mm-08 Remington

Remington Arms introduced the 7mm-08 in 1980 as a factory version of an idea target and bench-rest shooters had already been building as a wildcat for years: neck a .308 Winchester case down to 7 mm. The name says exactly what it is — a 7mm bullet on a .308 case — and the case stays 51.69 mm long with the .308’s own 11.96 mm base and 12.01 mm rim, so the round runs through any short action already cut for the .308 family with a barrel change and nothing else.

At a 7.23 mm bullet diameter and a C.I.P. maximum overall length of 71.12 mm, it splits the difference between the smaller-bored .308 Winchester it is built from and the larger 7mm Remington Magnum that came before it: less powder and less recoil than the Magnum, for a flatter trajectory and lighter report than the .308. C.I.P. rates it to 415 MPa; SAAMI’s figure of 60,191 psi, from a different test method, is close but not the same number.

Three loads are recorded here, all from the same encyclopedia ballistics table and all tied to a stated 24-inch test barrel: a 140-grain and a 175-grain Nosler Partition, and a 150-grain Speer Hot-Cor soft point — a spread that covers the round’s range from flat-shooting varmint and deer loads up to the heavier bullets used on larger game.

Gaps on this page: the table’s own cited source, an archived Federal Cartridge Co. ballistics page, is a 2007 snapshot rather than a live manufacturer page, so these figures should be read as historical rather than current factory specifications. No ballistic coefficient is published for any of the three loads. Neither DVIDS nor Smithsonian Open Access returned a result for this cartridge; it is a commercial sporting round with no significant military history.
