home Forums – The GUN Forum Ammunition Reloading I am currently depriming some range brass, mostly my own but some left by other shooters. I have some Norma 9mm brass that appears to have large pistol primers. They photo compares a Winchester/Herters (left) a regular Norma (middle) and a Norma with the larger primer (right).

    I suspect the casing on the right is berdan primed. I deal in OEM quantities of brass, any time I have seen a “large primer” 9mm it is berdan primed. Also the lack of headstamp is conspicuous with chin/com military produced munition (Tula, Wolf, Norinco, Etc)

    Always inspect your range pick ups. Could be an oddity, could be berdan primed, could be someone’s modified cases, who knows…? Spare your decap pin by looking b4 hitting the press.

    I’ve come across older small berdan primed .45 Auto cases. Some of the older R-P 7.62x39mm cases use small rifle primers, too.

    I’ve seen the opposite in .45 ACP having small primers but not what you’re seeing. Wouldn’t shock me though.

    I’ve never come across this in 9mm cases… damn. I do individually check each piece of range brass for the usual things, but have never seen something like this (beyond the typical 45ACP varying primer sizes). Good catch. I guess desperate times call for desperate measures; makes you wonder what else reloaders may be doing to make due nowadays.

    Just looking at the picture the one on the right looks like someone loaded it really hot. Pop the primer out and measure the primer pocket.

    Throw them in the garbage. If you’re having a hard time finding spp’s try out some srp’s.. hammer fired pistols will have a good chance at setting them off. Striker fire less of a chance. Ppl say certain brands are softer with cci being harder. I’ve had good luck with cci 400, but don’t even try cci 41’s

    Am I seeing things or has anyone else encountered this? I’ve searched Google and came up empty. Thanks in advance.
