Winchester dummy ammunition

[BOB IN AZ]

Hi, can someone let me know approx when this box of WINCHESTER-WESTERN DUMMY AMMUNITION WAS MANUFACTURED?

Not really interested what it is used for, just when manf.

TIA BOB

Just based on the type style and appearance of the box I'd place the date of MFR between ~ 1965 and 1980 - again only a WAG. I must quickly add... I am not a shotgun expert. But I shot away a bit of the live stuff in that time frame.

Have some that looks exactly like that, that we used for training our Marine sentries.
