I'm not aware of any .308 old enough to have corrosive primers, so I can't see what harm it could possibly do.
[/ QUOTE ]Western Cartridge Company made some .308 Win. match ammo headstamped WCC58 with 200-gr. FMJ boattail bullets; round top corrosive primers were used. This stuff was made under military/OlympicTeam contracts and was packaged in white boxes with black print and had the caution about corrosive primers used. WCC may have made other .308 Win. ammo in the late 1950' with corrosive primers.
Best and most uniform .308 Win. cases ever made. Too bad it had corrosive primers.
