Some interesting results today with the Heliboard and Labradar. I wanted to run the 18 gr JSBs from a full charge (230 bar) down to 140.

I thought the board would do a better job of keeping the velocities tighter over the pressure range, but that's not happening. Wondering if this is normal because I never ran the test with the factory board. Here's the results:

230 bar : 980 fps – one nice big hole at 25 yds. ES about 5 – very nice.

200 bar : 970 fps

170 bar : 950 fps

160 bar : 940 fps

155 bar : 930 fps

145 bar : 910 fps

140 bar : 900 fps – correction to keep the same poi = 1 MOA up and 1 MOA left

Does an 80 fps variance from top to bottom seem normal, or is the MCT not mapping as expected?

Thoughts?
