>Look at this fucking thing! How much lighter is it than 308? Like 5 grains from the case, 10 grains from the bullet, 5 grains from propellant? “Intermediate cartridge” my ass, that thing is a slightly nerfed full power cartridge.
Appearance isn't everything, moron. They were severely downgraded because the British were looking for a low recoil cartridge. Let's look at numbers.
.280 British performance
139 gr Ball, 2,270 ft/s, 1,595 ft/lbf
140 gr Ball, 2,549 ft/s, 2,019 ft/lbf
6.5 Grendel performance:
90 gr Speer TNT, 2,880 ft/s, 1,658 ft/lbf
108 gr Scenar, 2,790 ft/s, 1,866 ft/lbf
123 gr Sierra Matchking, 2,650 ft/s, 1,917 ft/lbf
Congrats, your weak-as-hell cartridge matches a smaller, more efficient cartridge; now look at this.
6mm ARC performance:
103 gr ELD-X Precision Hunter, 2,800.0 ft/s, 1,792 ft/lbf
108 gr ELD Match, 2,750 ft/s, 1,814 ft/lbf
Now, the numbers don't lie. Third time's the charm; your worthless, dogshit, pathetic .280 cartridge is weaker than an intermediate cartridge. Its large size, earning such pathetic velocity, only proves that it wasn't efficient either, and the country that invented it knew that as well since they stopped developing .280 British and were going forwards with .270 British instead (this was before they were forced by NATO to adopt 5.56x45mm). You got it this time, you imbecile?
