Bob - when you say 'scout type' gun for close in situations, what do you mean??? Are you going to cut down the barrel to make it look like a No.5, the Jungle Carbine? Are you going to leave the barrel stock length, at 26 or 27 inches???
I have a number of SMLEs and feel the No.4 Mk1 is the best. If you can find one made by Savage and marked US Property, you will have found one made in the US and never issued -brand new rifles, literally. If you find a No.4 Mk1 factory reconditioned by Fazerkly, or however it is spelled, it is almost as good as new.
The Indian made Enfield 2A1 is chambered for the 308; the others for the original 303 British caliber (which in my book does not take a back seat to the 308). I have used the 303 British on Whitetail, hog and black bear - I don't recall any of them running off.
You can scope these rifles much easier than you might think but I do not know if there is a scout type mount available. There are a couple of places that make rail mounts that replace the rear sight and set the scope closer to a sporting application than a scout type mount. In addition, the bolts on the SMLEs are already designed so they do not have to be cut and welded to mount one of the rail type mounts.
Aftermarket sporter stocks are available from any number of sources but for a general selection of parts and the like, including stocks, check our sponsors list first, those folks ahve alot to offer. HTH. Mikey.
