6.5x55 Dutch?

I am curious about headstamps on some 6.5x55mm Dutch.

One headstamp is 28 at 12 oclock and A65 at 6 oclock. The other is 29 and P in the same positions.

I checked the headstamp codes on the website and elsewhere with no luck.

Any ideas?




You have two Dutch 6,5x53,5R. cartridges.
The headstamp gave information about production-year (12 o’clock), code letter for the brass supplier (6 o’clock)
I don`t know the names of the brass supplier.
