Why specifically .308?
My PREFERED round is the 7.62mm
So versitile! And you can get both weapon and round for 1/4 the price of anything else.
I can get 1000 rnds of 7.62 for $88 all day, an SKS for $200, and a decent AK for $400
Just plinkers, and fun guns, not serious machinery. I turn to .223 and my AR for that!
but for all around fun a 7.62 just gets it for me, and neither my AK nor SKS has ever jammed on me....the only time it mis-fires is the occational bad primer on the ammo. Which is 1 in every OTHER 1000 rnd brick 
But anyway...back to your choice....why .308?
hunting?
damage?
cost?
A 308 is a 7.62 round. Actually it's 7.62 x 51
The SKS / AK 47 use the 7.62x39. I know I've owned 2 SKS's and a MAK 90.
My favorite gun is my Colt 1991 A1 .45 which I had customized by Wilson. I have the following done:
Wilson matched barrel (5") & matched bushing
New sear
Polish extractor
HD spring
Commander hammer
extended beavertail
Polished feed ramp
magazine well was bevelled
light weight trigger set at 3 1/2 lbs
finish is parkarized (original finish)
I have two sets of grips, well 3 actually. One is the Colt rosewood checkered grips, 2. Pachmyar wrap around grips, and the original (which suck). I also perchased 8 round clips (mine came with 7 round) with the rubber butt plate. The sights are trijicon adjustable (rear), fixed front.
I also own:
Marlin lever action 30/30 ( I have a Simmons 3-9 x 32 scope with it) Model 30AS
Maverick 12ga shotgun (black finish) (my Dad has this now)
Mossburg 500 12 Ga
Stevens 12 Ga (side by side) (Dad has this one)
Remington 1100 12 Ga
Ruger GP 100 blue 6" .357
Ruger Redhawk .44 mag (SOLD)
MAK 90
Ruger .22 cal 22/45 (KP 512) model (for target shooting)
Ruger P 89 (SOLD)

Also a NRA certified instructor (home defense / basic gun & rifle), and AA freestyle archer (own 2 target bows)
