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.

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.
