The truth is that a semi-auto such as a Garand, M-1A, FAL, etc. would be better. They combine range, power, penetration, and firepower.
But you have what you have and that is what you have.
Right now, I have four rifles that would fit as combat weapons.
A Savage 308, a milled AK, and two Finnish M-39s.
I want a FAL and I plan to get one soon, but I don't have it yet.
The Scout fires a more common round and it is a good, reliable shooter, but it isn't a combat weapon. After about four shots, the rounds start to walk their way off the target, up and right. I think that sustained fire with it may damage it, so it is out.
The AK works well and would hit hard close up, but I can't hit crap with it past two hundred yards. No good for engaging a superior enemy and getting away alive. It is out.
The M-39s are battle proven. They will shoot hard and far and penetrate what is in the way when they get there. They are accurate, reliable rifles.
They are bolt actions, and the Mosin Nagant action is even on the slow side of bolt guns.
But they have my full confidence and I would choose one of them if I had to respond to whatever right now, right here, this very minute with a column of Cuban troops approaching my hometown.
If an '06 and a .223 is what Weaps has, then that is what he has to use.
Can't fault the man for that.
