The first rifle I ever purchased (as opposed to what I inherited) was a Remington 788 in .308 Winchester. 1971. I think I paid $150 for it. I see them for sale today at $650. Amazing.
The stories I have about its tack driving capabilities are endless. On the range, in the field, it is still my go to hunting rifle. After my eyes required glasses I stuck a nice 4x scope on it (and that's 30 years ago!) and continued to rely on it ever since. No other changes; it's all original - oh, maybe I put a Decelerator pad on it a long time ago, just because I could.
Most years, when I take it to the range for zeroing, I shoot it at 100 yards, fire 3 rounds, get a tiny group right where I want it, so I put it away and shoot other guns. It's an amazing rifle. Of my long guns it's pretty much the last one I'd ever part with.
