Fiber cushion wads are tricky. I used 2 lubed cushion wads and no nitro card at all and created a load that tested at over 18,000 psi (average "only" 13,250 psi) while the same powder charge with 2 unlined nitro and one unused fiber wads tested at 5200 psi and only 660 fps.

Nitro wads, fiber wads, lube, and seating pressure are all interacting. In addition, the results from different makers of fiber wads have been wildly different. We have a lot to relearn about loading fiber wads. It's sort of like paper patched bullets all over again.
