However, this is not an essay on military ammunition development but a gun test, and though the 6.8 mm is interesting, I have my doubts as to its ability to out perform the 223 Remington significantly to make it attractive to the British sports shooter. So it would seem likely that if the switch is made from 5.56/223 then the SPC will be in the frame for the job. Though there are other and similar calibres in development and use, such as the excellent 6.5 Grendel, only the 6.8 SPC is a factory item with both Remington and Hornady making ammo. This would give the 40-year old M16 family yet another new lease of life. The idea would seem to indicate that eventually the 6.8 mm could become the new US Service cartridge and totally replace the 5.56 x 45 mm. This round has been developed to operate in an M16 platform and is said to offer more power/performance than the current 5.56 x 45 mm (223 Remington) ammo. It’s the second part that is perhaps of more interest as this LTR is chambered in the new calibre of 6.8 mm Remington Special Purpose Cartridge (SPC).

It’s a handy rifle that’s still capable of good short/mid-range performance. The LTR has a heavy barrel and decent synthetic stock, but does not come in the usual large and weighty package common to this sort of equipment.

This review is really in two parts, the first is very much a known quantity in the form of a Remington 700 bolt-action rifle, though this example is unusual being what is termed a Light Tactical Rifle (LTR).
