Any experience with Hornady Monoflex?

[HighCotton]

I'm thinking about trying these Hornadys for my TC Encore. The 50 cal sabot, high speed low drag with 45 cal monoflex bullet (250gr).
Just curious if anyone has experience with these on the range or in the field!?

I haven't used them. Can you find the specs for bullet impact fps? (upper and lower fps). For instance, some of the the Barnes bullets say they need an impact speed of 2000 fps or greater for 100% expansion, at impact speeds less than that, they don't have full expansion.

Some data showed that with the Barnes bullets, impact speeds less than 1800 fps gave no expansion whatsoever.

I'd rather see hard fps data from Hornady vs. "uniform expansion, even at the low velocities of longer range impacts".
