Like it or not, 'Scout Rifle' has entered the gun community's vernacular. Much like 'xerox' and 'kleenex', the origin of the word is much more specific than its current usage. For the Xerox and Kleenex corporations, this causes problems because copyright law requires them to protect their trade name. Because their trade name has become a pseudonym for their products- photocopiers (also photoduplications) and facial tissue- there is the danger that other companies may begin to use their trade name, robbing them of their name brand advantage.
Also similar to Mr. Cooper's problem is the fact that these companies' efforts are largely pointless and asinine. It is necessary for them to continue to hold claim on the language, but the genie is already out of the bottle- the words have become vernacular pseudonyms. Everyone knows what you're talking about when you ask for a xerox copy, a kleenex, or a scout rifle.
So, we get to Mr. Cooper having the 'right' to define his own term. That's all fine and dandy. However, it's just window dressing. Most everyone has an idea of what a 'scout rifle' should be. A .30 caliber bolt gun with scout mounted powered scope. That it fully meets the specifications that Cooper set down is neither here nor there; the fact that he isn't satisfied with the scout rifle he himself helped design is telling. 'Scout Rifle' is an IDEAL. That is, something to shoot for, and hopefully meet. The exacting limitations he set are a bullseye, but not meeting the mark is OK too.
He has decided that the Steyr product is as close as we're going to get to his 'Scout Rifle' concept, and that if we want what he considers a 'Scout Rifle', we'd better get one while we still may.
However, that doesn't excuse him for calling the near-hits 'pseudo-scouts'. He has decided that he sets the threshold to meet, and not even his Steyr has met it, apparently. The Steyr Scout is also a pseudo-scout, because it doesn't meet his full approval.
Thus, I must conclude that Cooper is suffering from more than a little hubris.
Anyway, I'm having fun with my current Mosin-Nagant carbine scout. Someday I'll convert a good-shooting M38 into my primary rifle. As for 'general purpose', specialization may be for insects, but they certainly outlived the dinosaurs, didn't they. Use the correct tool for the job.
