From the guy I bought it from I highly doubt that he took a BDL and converted it.

Mine says 7mm EXP REM, barrel is stamped 83, SN A68572XX. It does have screws for iron sights.According to what I found that is correct, ie they made the 7mm exp rem 1977-1983.
1981 classic 7x57
1982 classic-257 roberts
1983 classic 300 H&H
1984 classic-Can't find.

So from this, if I did buy it in 85 which I am 99% sure, they didn't make a classic long action besides the H&H which should be a different barrel contour I suspect, to swap from a classic caliber donor..??? And they didn't make the 7mm a classic, they labeled it 280 rem..
