    Ok I goofed again! Loading 9mm 124 gn jhp over 5.5 gn CFE Pistol. I was out of primers and bough a brick at my LGS. Loaded about 150 up before I noticed I had picked up The Magnum CCI 550 primers not the regular 500 primers.
    I think it will be ok as ammo is loaded at mid range for powder (max 5.8 gn) and will be shot out of a Hi-Point rated for +p ammo.
    Opinions?
    Chute EM! or scratch and restart with correct primers?

    Some primers serve both regular and magnum loads so if the reload is mid-level then it is probably (?) OK. Inspect the empties from this batch after the first couple to be sure the brass is not overworked (flat primers, blown primers, ballooned cases, splits).

    Some reloaders here interchange primers in a pursuit of a more accurate load. Some spherical powders require a magnum primer.

    Now, this is my logic for my reloads and not really advice to you. Shoot this ammo at your own risk and not mine.

    Those are rookie numbers...gotta pump those numbers up! 5000 is a good starting point. ;)

    Take a dozen rounds for each (500 and 550) and see if you can tell the difference in feel and accuracy using a rest.

    these are not part of my normal stash.. your starting point is well below my preferred low stash limit. these are "EXTRA" for son and family.. I dropped off 10,000 rounds 2 yrs ago there.

    What drymag said.

    I've used CCI mag and CCI normal primers in my .357 rounds...these are not .357 magnum loads. I could not tell much difference between the CCI 500's and 550's using Titegroup and 158gr RNFP bullets.

    What LD said...shoot cautiously, checking the brass for stress.

    The Hodgdon website shows 5.5 grains of CFE pistol to be a max load for 124 grain bullets. http://www.hodgdonreloading.com/data/pistol
    If I were you, I would go back and load some with the magnum primer starting at 4.9 grains, and work the load up to the 5.5 grn load. Stop if you see signs of excessive pressure. It's the tried and true old rule of "change any component, go back to the starting load and work it up". Of course, I tend to be cautious when I'm reloading. I would consider how you would feel if your gun blew up in your grandson's hands. Think about it.

    This reminds me of the owner and gunsmith of the range I go to , God rest his soul. He always used to say that when you reload start at max and than add a couple of grains until you get pressure signs and than back off a grain. He was a great guy and gunsmith but was to scared to follow his advice.

    Excellent! But I was referring to the amount you were taking to the range for shooting. 5000 is just a good starting point! ;)
