No mistake. I am a pressure fanatic. Afterall, without it, bullets don't move!!!

But I appreciate your concern. The guage read in Copper Units, not PSI. I am aware of the new SAAMI listings. I like PSI better. It gives the avg joe shooter a better mental comparison factor than the CUP did. Most didn't have a clue what a Copper Measurements were or how to visualize them.

Good Post.
