“Mosin-Nagant”
My cousin spoke very highly of these, he purchased one and also mentioned that the market is flooded with them which means they are less than 100 bucks.
You could also probably get a pallet of ammo for another $100.
If you want to improve the odds of buying an accurate Moisin-Nagant, buy a Finnish one, not a Russian one. Russian quality control was wretched at times. The Finns captured and bought a lot of Russian M-Ns and rebarreled them. A difference of the barrel bands enable you to tell them apart.
