Long story.... A very respected, former military man and now "guru" of the rifle world (Col. Jeff Cooper) came up with an idea for an all-purpose rifle (as near as could be designed). This occurred a number of years ago. Col. Cooper decided that the rifle should fit certain criteria.... such as :
1) No more than 1 metre long.
2) Relatively light in weight (I think about 6.5 lbs, complete).
3) Bolt - action.
4) Equipped with a shooting sling (three-point attachment).
5) .308 calibre (easy ammo availability/ current mil. cal.). 6) Equipped with a low-power, long eye-relief scope,
mounted forward of the receiver (so to facillitate shooting
with both eyes open and allowing for quicker target
aquisition - which this set-up does nicely).
7) Removable magazine (to make reloading quicker).
8) (Optional) back-up aperture sights.
9) (Optional) bipod, for use as required.
Those are the basics. This was not really intended as a military weapon - but, as Col. Cooper has a military background - some quasi- military aspects creeped into the design (such as the removable magazine.... most people do not need quick reloading while hunting). Since the publication of this "scout rifle concept", there has been debate within the rifle community - some hate the idea and think it is bogus, others embrace it. Really, what it all about is a light (easily carried), accurate (out to 250 yds), practical rifle. I think that most of the controversy surrounds the forward- mounted, long- eye relief scope. Many seem to hate the idea.
As for my interest, being the free-thinker that I am, I was intrigued - though I do not regard Jeff Cooper as some sort of God.... as some do. I never set out to exactly duplicate ALL of the aspects of his design... I have omitted those items about which I simply don't care (removable magazines, bipod, aperture sights). I did wish to try the forward-mounted, LER scope.... which, for all-round use, I like very much.
Of course, just as with any device, there are compomises. The scout rifle is not a perfect creation - nor is it a do-all weapon (nothing of that sort exists). It is different, which appeals to me.... and I have found mine very handy and pleasant to shoot.
A word about scout rifles available to the public. There is, at this time, only one such purpose-built scout rifle manufactured by a gun company. That is the Steyr Scout. These are about $2500.00. For a time, Savage offered their own version (quite a bit simpler than the Steyr Scout), but they have discontinued it. Most people who are interested in a scout rifle construct their own - (all kinds of different brands/ models have been used as the basis for these). The scout rifle is still somewhat of a rarity - many people haven't heard of this.... many others who have don't care for them. They are "an aquired taste" , I think.
