[QUOTE="Guest, post: 117937"] I plan on ordering one soon - I think it's an interesting tool. The achilles hill of the [url="http://www.shootingsoftware.com/pressure.htm"][b]PressureTrace[/b][/url] is calibration. But if you knew the pressure of a load, you wouldn't need PT. [ QUOTE ] [b] As is normal for me, I adjusted for the maximum sensitivity. WaLaa- Pressure trace displayed. Wooo Hooo. ... I did note a bit of a secondary pressure spike about 3/4 way down the trace. Interesting, says I? I don't like those things though I hear they are normal for the RUM cases but don't have valid data, yet.[/b] [/ QUOTE ] The 2ndary spike is likely an artifact of having the gain too high. I'd back off the gain as much as possible, otherwise you're amplifying noise and subject to artifacts. I plan on calibrating my guns by increasing loads until I see physical pressure signs. Once the unit is calibrated you can more easily compare powder, primers, loads at various temps. [/QUOTE]
