If you have some pressure estimates to provide, I'm interested in them, and how you calc'd them.

I know my rifle. I've put several thousand rounds through it, and developed a number of loads up to visible ejector flow, then back off a bit. I always see some of this flow before primers are showing abnormal flattening (see pic of brass posted earlier here).

Having 20+ reloads in the same brass gives me a good indication that pressure is fine with my working loads.

I only have up to five reloads on some test brass with this RL17, but so far no loose pockets.
