Pete,

These loads were in measured using a 10 gauge and a Pressure Trace II.

The PTII works as long as one has a standard (reference load) to calibrate it to. Also, precise measurements must be taken of chamber thickness. The process is a pain in the butt but given a day to dabble with it good results can be obtained. I like it for starting with a good loading data such as that from a Lyman manual or Sherman Bell's research. Those are my standards (actually approximate references and certain not a "Standard"!) from which I experiment with a change of primer, shot, wad or so on...

Last year I used a single barrel American Arms as my test gun. I recently obtained a Marlin Super Goose 10. The gun is like new and it will be a shame to glue the strain gage (sensor) to the chamber. I also bought a simple return to battery cradle to save my shoulder! Now all I have to do it to build a bench strong enough to mount the rig to!!!

As you might guess this part of my hobby is getting expensive but it's at about $20k less than a real test barrel, universal breach, and Ohler pressure measuring equipment.
