It doesn't sound like the MAS in 308 is for me. I like them because they look unique and I like a new toy every so often. Sounds like I would not be so happy with a Froggy in 308.
I think for a cheap foul weather hunting rifle, it's hard to beat the NEF. If you like a bolt action, Mossberg has one for short money. You can pick up a low dollar sporting gun that is new and made by an American manufacturer who is still in business for less than the cost of buying and sporterising an old military rifle. If you like doing that for the satisfaction that's one thing, but to save a buck it's often not worth it. I 'sporterised' a Mosin Nagant type '38 a couple of years ago. Starting with a $100 rifle (that's a good one as MNs go), had the bolt bent to clear a scope. Drilled and tapped the receiver, bought a mount, refinished the stock, so on. By the time I was done it cost me within a few bucks of a new Mossberg ATR or I could have just flat out bought another Handi rifle. The Mosin still shot like a 70 year old war horse. Not terrible, but not great. I was a little disapointed because I had wanted it as a low dollar hunting rifle and I ended up with an over weight beater that didn't shoot well and wasn't as low dollar as I had planned.
This year I got a well used but not abused Marlin 30-30 for $200, which is less than I spent on the Mosin Nagant. I'm much happier with my Marlin.
Point is, while it used to be that sporterising a Mauser or Enfield was a cost effective way of getting a hunting rifle, that is less true as the value of the moldy oldies goes up and the availability of used and entry level new guns is (for now) pretty good.
