bolt 7.62x39
Whatever bolt x39mm rifle you get, I think you will find it a practical, useful and fun firearm. I've owned one for 15 years or so, and hunt it every deer season, within its range, it's worked very well for me on woodland, southern whitetails. Even if I don't see game, the little rifle is a delight to carry hither and yon,and its stainless/synthetic make up makes for easy maintenance and cleaning, especially in the wet.
Whether you load for it, or shoot factory ammo, it is still relatively cheap to feed. My bolt does not get import steel case, but it still uses about half the powder charge of a .308, twice as many shots per pound of powder. Fast and flat enough for useful practice to 200 yds, it will not beat you up with noise and recoil.
I bought the rifle as a starter (deer) for bamaboy but he took to the .243 instead pretty quickly, and never really warmed up to the x39mm. If and when he hunts now, it's all .308......leaving that tidy bolt x39 for me.
I consider it one of my "better buys" and would not want to be without one.
