I use the standard 9 1/2 primer, not the magnum 9 1/2m primers.
My Norma brass holds 86.3gr or water, you can compare that to your brass internal capacity. As opposed to some other brass I had (can't remember Rem or Win) that only held 82gr's. This is why it's so important to work up loads with your own components. I am sure my current load in the smaller brass would be horribly over pressure.
It is likely that you will be around the 3000fps mark somewhere in your 63-66gr testing with the magnum primers. If you end up weighing how much water can be held in your brass, let me know, as I'd be interested.
Thanks and good luck
