Well Sir, if it is the M48bo's you're referring to, they are "pricey" because they are a 60 year old rifle in mint condition, still in the cosmoline they were first dipped in after production. Only one person is currently importing them, so they set the price.
They are amazing rifles, I owned one for a while. We parted ways when her feeding habit became to pricey alas
I am a guy who likes to actually fire my guns, 8mm Mauser is an awesome round, but for the amount I shoot, I couldn't afford the price unfortunately.
If you are a hand loader, you can not go wrong with one for the current price though.They probably won't get cheaper with time you know.
