"Doesn't that kind of scope limit your field of view much more than a scope mounted with closer eye relief?"
No. It actually increases your field of view because you very quickly learn to use both eyes. The caveat is the scope must be low powered and mounted correctly. Most attempts at "scouts" have the scope too high and too far forward. If mounted correctly when the rifle is shouldered and a correct cheek weld is taken the shooting eye is looking through the scope imediately. You should not have to raise your head or search for the field of view. It should just "be there". If not the scope is not correctly mounted.
I have been using scout rifles for quite a few years. I currently have three bolt guns set up that way. One has a 1.5X Burris, one a 2X Leupold and the other a 3X Burris. I have also had a M1A set up as a scout (pre "Bush" rifle) and a M94 Winchester. I have also used the Steyr and the Savage scouts. All are very good set ups IF the scope is mounted correctly. Factory bases were used on the last four rifles mentioned and all were good and correctly positioned the scout scope. However, all of the commercial scout bases I have seen for milsurp rifles are abomonations. They all mount the scope way to high, even with the lowest rings available. Another abomonation is the "lets" use a cheap pistol scope as a scout scope concept. Haven't found any regular pistol scope to work because the eye relief is too long. consequently the scope can not be mounted correctly.
I also have a Spanish Destroyer I mounted a Tasco red dot sight on. A TC Contender weaver style base was used as the contour fits the barrel. I really like it and it is great for jump shooting jack rabbits and general plinking. Only one problem, I let my wife shoot it and now it is "hers". I just get to load the ammo and clean it, no respect....
As I sit here in Iraq I have my M16A2 laying across my lap. It has a C.R.T.C. adjustable (elevation) mount on the handle that puts the EOTech forward of the handle and low (I actually filed some of the top of the hand guard down) on top of the hand guard. Both were my own purchase. I have the iron zeroed at 300 meters and the dot of the EOTech co-axial with the iron sights. The 1 MOA dot sits just on top of the front sight when I aim through the sights. With the dot center mass the zero is back down to 250 meters which I prefer. I can use the small apeture for precission shooting, the large aperture for quick shooting out to 200 meters or look across the top of the rear sight and just use the dot for CQM or the other two for that matter. All three methods are very quick and extremely accurate. Setting the dot shoulder level takes targets at 400 and just on top of the head will drop them at 500m. When I return the EOTech with be tried on a couple other rifles including an M1A but most likely will rest on my AR15. It is a very nice set up and I'm betting will be the cat's meow for calling coyotes.
" Is it a significant amount?[/quote]"
No. See explanatin above.
One last caveat. I do not say that the scout type rifle is the end all and obsoletes all other types of hunting rifles as does Jeff Cooper. I do agree with him that it is a very useful concept with in it's limitations which are very few. I do still have and use rifles of other more standard configuration. However, I must say that my scout rifles are creeping more and more into my hands when I go hunting. Especially when ranges will not exceed 300 yards. That IS most of the time now isn't it?
