Pretty sweet toy that I could spend hours being a dweeb.

There was a guy on Glock Talk that got the system and was going to use it, but last I saw he had it up for sale not long after he purchased it.

The strain gauge is said to need to be on a rounded section of the chamber for proper readings...the TC is what the fellow on GT was going to use.  I had thought of a fixture I could mount a spare barrel for my 1006 in to take readings should I buy into the system.

You need to calibrate to ammo that is known to yield a pressure value, however it is still guess work!

You gunna buy one?

According to the site:

PressureTrace will generate PSI estimates without calibrating the system to a factory load!
Using factory ammo or a load reference with known pressure to verify results is always recommended but we recognize each chamber will produce different pressures and wildcatters may have nothing for comparison. PressureTrace uses both thick and thin wall open vessel algorithms to provide reasonably accurate pressure estimates from barrel, chamber and brass dimensions. Unlike other products PressureTrace does not require a large correction "fudge" factor for pressure held by the brass but the system can still be calibrated to match other pressure systems. For safety, NEVER exceed the loads in a reputable load manual.

I have Quickload for estimates, but nothing's perfect.  The Encore would the test bed.  Maybe I'll be able to afford a 10mm stub barrel when Bullberry runs a sale.

I shouldn't.

Can I borrow a few bucks

Greg

Now I need to order a couple barrels from Bullberry. 

The sane one will be chambered in 10mm.
