Starting with a .450 Bushmaster case, Remington trimmed the length to 1.525 in from the original 1.7 and necked it down to accept a conical .308 in diameter bullet with a 25-degree shoulder. [ 4 ] The rim size is .492 in and because the round generates 55,000 psi, Remington opted to use a .308 rifle bolt in a 5.56-sized rifle for increased case ...

The 7 mm version first appeared around 1980, with the .25 caliber appearing in 1987. The larger calibers provide more downrange energy, and resist wind deflection better than the original .22 caliber (5.56mm) bullet, and the moderate case capacity of the .223 Remington works well in the short pistol barrels.

The .30 TC (0.308 in (7.8 mm) x 1.920 in (48.8 mm) is a non-magnum that is somewhat shorter and wider than the .308 and .30-06. [1] The .30 TC has speed and energy equal to the .30-06. [7] All three cartridges weigh approximately the same, but the .30 TC produces less recoil. The case length of the .30 TC is 1.92 inches.
