Thanks!Probably late 50's early 60's. Herter's was pretty big back then.
I’ve got some in 6mm 85 gr I bought off here. I shot them with about 1” groups which should be good enough for some hunting or be real good for fire forming. Mine has same label as yours.Thanks!
I just found a Herter's shell holders and a cartridge gauge!Used to love looking at their catalog when I was a kid. Everything they sold was the world's best!!! Lol.
Agreed. The label shows a zip code. USPS started using them in 1963.Mid-late 60s

I have a couple boxes of these in 150gr. Just need to watch seating depth.Herter's Wasp Waist Bullets

$4.39 may look so super cheap today but try to remember that minimum wage at the time was $1.25 per hour….
