Savage Short Action w/ Detachable Mag
I haven't personally done this, but it was posted on another board that it is resonably easy, without special tools, to modify a Metric FAL mag to work in the Savage Short Action rifles that use detachable box magazines. As long as the mag fits in the well I can believe this, since all that is needed is to cut a slot in the side of the mag at the correct location to engage the magazine catch lever. I bought a Savage 11FC with this in mind but haven't gotten around to it, and have kind of lost interest in it.
I tend to agree that a hi-cap bolt gun is of questionable use to a lone fighter. Shoot and scoot is the correct game plan if you don't have back-up. The Enfields were designed for coordinated high intensity vollies during trench warfare, not for sniping. If you think that you will need to engage lots of targets in a short amount of time, by yourself, get a semi-auto in .223, lots of spare mags, a flak-jacket, kevlar helmet, and learn how to pray.
