RE: Ruger M77 RSI .308 Win.
I' ve always liked the looks of the RSI, but never bought one. I fear the full length stock would cause accuracy problems if it ever got too moist and warped. It gets damp here in Oklahoma. Humidity alone is usually above 65% even on sunny dry days.
Being it' s a 7 lb rifle, it shouldn' t kick much with the .308. Add another 1.5 lbs for scope, base, and rings and it weights the same as any other sporting rifle. Muzzle blast shouldn' t be much of a consideration either.
If you like it that much, and will use it only occasionally, I see no reason why you shouldn' t buy it.
