HP and MEN headstamps variations on modern hunting cartridge


#1

I am checking all my headstamps and I found some variations in the basic HP (hirtemberger) headstamp on modern hunting cartridges.
The same cartridge (6,5 x 57R) has the following:
HP 6,5 x 57R
HP2 6,5 x 57R
HP3 6,5 x 57R

(numbers 2 and 3 are smaller than the letters H and P)
What do these numbers mean?Lot?Date?Bullet weight or shape?

Also the MEN headstamp on 6 x 62R Freres cartridges have a variation:

MEN 6 x 62R Freres
MEN * 6 x 62R Freres

Has this little sign a meaning?

Thanks

Pivi–The small numbers are the year of production. They were used from the 1960’s through at least the 1970’s. The only caliber I had seen them on until your posting was .22 Long Rifle. I have full boxes of all the numbers from 0 to 9.

I am not sure but I should have these headstamps also on othe cartridges like 6,5 x 68 mm.Tomorrow I will send a picture

I can only add a little more detail, not much in the way of answers:

Re the Hirtenberger codes, these are known on at least 14 HP European sporting calibres including:

5.6x50R
5.6x57 5.6x57R
6.5x54 MS
6.5x57 6.5x57R
6.5x68
7x57 7x57R
7x64 7x65R
8x57JS 8x57JRS
8x68S

The exact meaning of these codes does not appear to be known for sure, even in Austria. Josef M

In the munition.org website is pictured a HP3 222 rem headstamp.
There is written that the number 3 represents the bullet type

At least on .22 LR I am positive the numbers are dates. I have .22 LR solid and HP with the same numbers. Also, all the numbers 0-9 are to be found and ONLY those numbers. I would need to dig out my .22 collection, but I think I also have the numbers on .22 Short as well as LR.

I can not imagine that the numbers mean one thing on .22’s and something else on centerfire rounds.

Pivi and Ron, there may be others but the only 22 short I have with HP subnumber is HP 8. the rest are on 22 long rifle, 22 WMR and a couple of tool blanks.
