loose primers

Have some fired once French Military 7.62 cases. I know once fired because the crimp was still there. After processing the brass and then seating the new primers I noticed the primers are loose in the pocket. If I blow into the case the primer moves so I believe these are way too loose. Pretty sure I should not finish reloading these but what about the ones I already put the primer in? Carefully decap and then save the primers for some other case? Scrap the cases or try a different package of primers? I have reloaded some of these same cases with the same size of primer without this problem.
Primers are CCI200.

    been using win lg mag rifle primers in new win brass, 25-06 rem. after 3-4 firings, wanted to try fed 210M and found them to be very loose when trying to seat. a few fell out so removed all.went back to win mag lg rifle and got nice snug fit, none loose.any thoughts,ideas suggestions on this issue? thanks.

    While the nominal dimensions are set by SAAMI, there are tolerances allowed. It is not at all uncommon to discover that components from two different makers don't match up well. You could get a "minimum" batch of brass and a "maximum" batch of primers - or vice versa. Other batches bought later or earlier could be the exact opposite.
    I may be a bit crazy - but I didn't drive myself.

    I have found that the older CCI 200 primers were a tight fit in most brass while the new ones don't cause me any trouble. I still have a few hundred of the old Winchester 8 1/2-120 primers and they are a very tight fit. I measured some primers with a micrometer a while ago but I didn't make notes of the results so, of course, I can't remember what they were. A half-thousandth makes a big difference!

    thanks for the great replies/info. guessing i should not try and fire fed 210m's in these cases.would i likely encounter this problem with a new batch of brass?

    You never know. Your next batch of cases may have been made with a new set of punch tooling and produce larger pockets - or with a set about to be retired and worn enough to produce pockets at the small end of acceptable.

    Ditto goes for new versus worn primer cup punches!

    I once had a batch of primers so large that I actually reserved them for cases that I'd loaded -- well, to their fullest, if you get my drift. Those primers simply wouldn't go into normal cases. I managed to get a few more loadings out of that brass. With "saner" charges, let me hurry to say.

    Ahh yes, the good old days before piezo electric pressure transducers. I would imagine Corporate lawyers got spontaneous grey hair when they saw the PSI pressures when using recommended loads in their companies data books.

    Remember that load from the Speer number ten manual pushing a 110 JHP out of a .357 mag with 2400????? [;)] WOW MAN WOW!!!!

    It was Speer #8 that REALLY had hot loads. They didn't use any pressure gear for handgun loads back then, and didn't even use copper slugs for all rifle loads.

    Worse, one batch of copper slugs came with the wrong correction tables. As a result, the loads tested with that batch of slugs tested low. The lab guys kept adding powder until the pressure reading came out where they expected. Some of those loads actually develop 75,000 psi when tested today on piezo gear.

    You can check them with a micrometer and report your findings to the company. They may actually be out of spec since production of primers for the last 4 years has been a 24/7 activity.
