@375 Ruger Fan I respect your viewpoint but you appear to have misinterpreted my words. The .308 Winchester cartridge was designed to equal the performance of service .30 cal (.30-06) ammunition. The Ordnance Department was ordered to develop a shorter, lighter cartridge with less recoil and better feeding and extraction than the .30-06 BUT they developed a shorter cartridge, with less body taper, a steeper shoulder angle and minimally less weight, that did not feed as reliably as the .30-06. They actually started their search for a new .30 cal cartridge with a rigorous scientific analysis of the 7.5x54 cartridge but ended up with (essentially) a lengthened version of the .300 Savage cartridge. The sole concession to feeding concerns was a shoulder angle similar to that of the 7.92x57 IS (8.2x57 in CIP civilian terminology) but with a shorter and straighter case!
They could not honestly claim to have abided by their instructions so ... they got the Winchester Repeating Arms Company to introduce the cartridge to the world (the only time that a service cartridge has been developed by the military and then launched first as a sporting cartridge) and lie on their behalf.
Yes, the .308 Winchester can be made to feed properly but it takes more work and expense. You may recall that, prior to the introduction of the AICS chassis system for Remington 700 rifles, the default detachable box magazine for bolt-action .308 sniper/sharpshooter rifles in the Western world was the M14 magazine, developed with plenty of U.S. government money! You may also have seen an article about Sturm Ruger's consultation with **NOT**PERMITTED** on their Scout rifle, wherein it was stated that **NOT**PERMITTED** staff advised Ruger not to use the M14 magazines that they had fitted to their prototype, due to unreliable feeding from cheap copies of those magazines.
When the NZ Forest Service cullers changed over from .303 to .308 Win. (and later .243 Win.) they quickly discovered that the Sako Forester was the only rifle worth having as a work gun. Sako put in the extra effort to ensure reliable feeding and are still renowned for making top quality magazines for their rifles. Steyr also made good magazines but their rear-locking action appeared a bit later and was more expensive.
I started shooting with an SLR L1A1 at ATG (Waiouru Military Camp) and am well aware that the .308 Winchester / 7.62 x51 (and its offshoots) can be made to feed properly. I have never said otherwise in this forum BUT it was not designed with reliability of feed as a primary concern. I also spent 14 years running a club range complex with plenty of help from other people and encountered numerous incidents on the range and heard numerous stories of feeding issues with cheaper rifles. My Winchester Model 70 short-action Featherweight in .308 Win. had a less than perfect magazine because USRAC was too stingy to make a proper one (like those in the pre-64 Model 70 that Brno copied for the ZG47 and ZKK rifles) and in my experience Remington Arms and various other companies at similar price points are just as bad.
