I had a Ruger GSR. It was very nice. Decent trigger and shot well for hunting or SD. It was a little heavy. The forward mounting scope deal limits a lot of what you can do with it. Iguess it just depends on your needs and planned use. If I was really looking for a SHTF scout rifle I'd just get some form of AR in 308. If you just want a light, easy to carry bolt action I am not sure the scout concept is all that. I kinda like my little CZ carbines. For cheap grap one in 7.62x39, and buy a bunch of steel cased ammo. Then grab a some good domestic ammo for SD or hunting. Lots of choices. I have a Leupold VX 3 1.75-6x32 on mine that I think cost about $300. Decent for the ranges you are talking. I have a Redfield 2-7x33 that is about a $150 scope that works OK too for that distance.
You could get a Browning BLR in 243 and do a forward mount optic. Not synthetic either though.
Or you can grab a Ruger in synthetic stock for a few $$ or a Steyr for more $$. The .243 is the sticking point. You'll probably have to put that together or buy a custom rifle. I'd stick with 308 or something more available if it were me. No sense reinventing the wheel unless you have lots of time, money and 243 reloading supplies.
Lots of choices depending on your budget and specific preferences. And how much bubba home smithing you might want to do.
