Played with my Ion today, and had some issues. Had exteme drop off when shooting more than 2 bps. I messed with the dwell and rate of fire settings and got it so it would shoot with out drop off, but the range was horrible. I'm talking 25-30 yards off rental and Spyders from Walmart. Any ideas out there of where to start my adjustments? I set the dwell at 48 and the rate at 0. I first started at dwell 40 and rate 8. I was shooting between 275-292 at the chrono.
