I would suggest going stainless 308 CTR. It is a proper rifle with a decent mag system for which you can get a huge amount of aftermarket bits to customise if needed. The 308 doubles as a fun rifle to shoot 800m+ or as a precision hunting tool. I have been using mine since two hunting seasons and love it. The bare rifle weighs as much as a heavier sporting rifle such as a Mauser M03.
My rifle is fitted with Bipod, heavy PMII scope, Spuhr mounts, suppressor and the stock has NV mount but otherwise light weight carbon. I am 55, very overweight but still prefer to carry this rifle over lighter weight 308's I have.
On Sunday first light I started in the valley across the hill, walked over, shot two deer on the top, filled the Rucksack with the meat and waddled down into the valley. Very wet... soggy... boggy ground. My CTR has taken deer from 20m to 550m. We shoot deer every Sunday from Sept till end Feb.
