The minimum dwell is 5 ms, and each blink corresponds to 1 ms. If you have a QEV (and I believe the Blackheart G1's come with those but don't quote me on that), than you can possibly get your dwell as low as 14-15ms, but in my personal experience I find that 20ms is the lowest I want to go without a lighter aftermarket bolt in addition to the QEV. Depending on your setup even that might be too low. There is a youtube video with Hans Semelsberger about how to adjust the dwell on GOG/SP guns, try looking that up. I would link you directly but I'm at work right now and youtube is blocked.
