That's another great review by Donnie.  I hope H&N fixes the issue because I haven't hear of anyone getting great accuracy out of the pellets except for one .177 rifle Ribbonstone owns.

Thanks Taso!  It's my pleasure!

Indeed, I hope they fix the issue as well.

Probably gotta get em moving pretty fast

Taso1000:
The .177 version needs about a 1 in 10 teist barrel at around 900 fps.  There is a calculator that works with subsonic velocities:

Just enter the measured values and it will output a twist rate versus velocity graph.
