[QUOTE]They probably are still just fine. When using fast burning powders you are not likely to see much change. Slower powders tend to get the higher pressures with mag primers. If you are loading near the top end you really should back off your load and work it up again slowly and watch for pressure signs. Low to mid range loads are not so much a problem. When in doubt just reduce your powder level and work the load up again. Doing things safely might take more time but in the end you will have more time to do other things as well.
Now I am confused.
I've been asking this question and getting conflicting answers. I've been told never to use sm pistol magnum primers in 9mm or .40. I've also been told not to substitute them when using fast burning powders. I'll ask this question strait up.
Can I substitute sm. pistol mag. primers in 9mm and .40 while using Titegroup powder if I'm using min.(starting) powder charge?
My apologies to the OP for the highjack.
