Hmm seeing as how the machinery that the No2's are made on was British and now gettin very old. AND Indian steel is very varible in quality from my persoanal experience having to machine the stuff after our buyer brought it thinking he was saving money
it was so poor the job too about 5x as long and we had to introduce new operations to get around the materil problems.
I doubt very much that the Indain made No2's are higher quality steel than the other N01's mae elsewhere. Also do you not think that it's possible AIM are marketing the .308 to make it more appealing to American shooters? And not only that there is no such thing as .308 Nato!
It's 7.62x51 Nato so it seems that AIM do not know what they are doing after all
. Now if you wish to risk shooting higher pressure rounds through a possible dubious quality rifle then may God watch over you. Me I won't touch them with a barge pole
