Received my DW .30 yesterday. OMG! 1st thing I found, the trigger is amazing, factory set I'd say it's the best trigger I have on any PCP's or powder rifles I own. The only other trigger that comes close is the CZ-527 single set trigger. After watching a lot of videos I was up to speed on the LCD interface with only a few questions which I answered by referencing the videos I'd watch. Now it's intuitive, and I'm hooked. The integrated chrono makes adjusting this rifle a breeze. Today is Adv. mode fine calibration and zero the scope. My intention is to find the most efficient setting to not waste air and push slugs out at around 950 fps. To do this I'll start with Voltage at 80, open the valve as quickly as possible, start with timing at 2750us /175bar. After shooting a set I'll increase to 3000us, if the speed goes up i'll increase to 3250us, if it stays the same I'll go down to 2650us. I'm looking for the setting where the valve time dwell gives me the fastest speed which I interpret as the optimum setting to open the plenum. Any time beyond this setting with no speed increase is a waste of air, any setting below this doesn't maximize efficiency which I interpret as optimum volume to fill the barrel at pressure without overfilling the barrel (i.e. waste air). I'm assuming the electro-mechanical repeatability of the rifle is spot on.
Out of the box I'm impressed. Hope the accuracy impresses as much as the rifles cutting edge design.
