Pretty accurate summation by SD.
A good aftermarket barrel will stop the brass from bulging so you can reload it a few times. This is kind of important as you usually don't find much once fired 10mm brass lying around at the range.
I tried most of the recommended powders and found 800X to be the best also. Happy shooting,
