    Thanks for the info.
    I’ll do up a few of my 124gr Campros with the usual 4.1 and wait for a warm Northern Manitoba day to Chrony them and adjust.
    Usually I just plug and play primers but this time I’ll do due diligence.

    I personally just use whatever I can get. I just chrono my loads I use for matches with the primers I am going to use at the match and dont worry about different brands for training ammo.

However, the load data all shows either CCI 500, or Winchester SP, for primers.

    I haven't seen those locally at all, but have seen Remington 1 1/2, and Federal Champion, and Federal Gold Medal. How much difference would it make if I used a mix of those, rather than the CCI or Winchester primers shown in the load data?

    Thanks in advance, for any help.you can provide.
    I don’t shoot 9mm, but I know a couple of shooters who won’t use Remington 1 1/2s due to the thin cup (which makes it perfect for my .38s)

    The literature says they can be used in 9mm, so maybe the folks I know are exceeding SAAMI MAP.

    I found two bricks recently and need to hunt for more.

    BTW, if you’re in D/FW and pick up some 1 1/2s, I’ll swap 1-1 for 5 1/2s. I have a large quantity of 5 1/2s, but I shoot DA revolvers and the primers are quite hard. It takes a full power mainspring to light them off consistently.
