My first gun was a Savage model 72. I was 12. Back then i could jump on my bike go into town and buy my own ammo at the hardware store. It was a 3-4 hr trip so i would get as meany rounds as i could carry. At least 3-250 round boxes.
I still have that gun. It looks just like it did on day one. My gun smith looked down the barrel and estimated that there have been 20k rounds through it. He is probably right.
