    R`p head stamp difference any one have knowledge ?

    Greetings,
    sorting thru some 44 mag brass to prep and load. What is the difference on the R-P brass compared to R(dot)P brass? have noticed this on several different calibers most recently 243 winchester and 44 Mag.

    How long ago was Browning making brass? ran across a couple 44 mag brass with Browning head stamp ?

    thanx

    Browning was in the 70's I think.

    I can't speak to the 243 cases, but to the 44 Magnum I have a quantity of both. I don't keep records that detailed, but just looking at the cases it appears to me the ones marked "R-P" (R dot P) are newer. The font for those is larger, the impression is deeper and they seem to be less prone to being made illegible from repeated shooting. I have this vague feeling I bought them as new unfired brass, but that's nothing to take to the bank.

    When I bought my BHP in April of 1970, I also bought a box of 50 browning 9mm.

    R-P to R*P was made in about 1970.

    Bought a batch of new, primed norma 30-06 brass last year with a browning headstamp. No way to tell how old they might be though.

    There was also a "recent" (~5-8 yrs. ago?) run of R-P brass distinguished by a different font on the headstamp and whose dimensions were slightly off. I.e., the extractor groove was somehow different enough so that the extractors in my '06 (Mod. 70 Win. Westerner) and 8mm Mau. (claw type; reformed '06 brass) would often not do their job. Mid-range were especially vulnerable, but I experienced this again the other day with a light load with a plain based CB too.

    The minor headstamp changes can be used to mark production that was sub-contracted out. Happens quite a bit.
