If you buy a 1968 .308 that has never been fired it will be worth quite a lot more than a last-year .270 that's ridden behind the seat of a '93 Ford 4x4 since 1987.
How do you do that?
Last year of the tang safety...and I might have that slightly wrong...
. Just mean that the tang safety 77's just before the Mark II's that have been hunted hard and worked outdoors won't sell as much as an unused early production model.
Incidently, I have a flat-bolt .250-3000...and no, it is
not for sale...
