Some data for Hobby and H&N FTT
Note: I only have Hobby in .177 and H&N FTT in .20

But out of interest: Hobby lost 53% height in the crude pellet test, FTT lost 34.6%

In the rod test: Hobby lost 28% and FTT lost 23.8%
Re-reading my earlier post I note I did not give data for Marksman. They actually turned out to be the softest rod, losing 34.9% height, just pipping AA Field at 33.35%

So in rank order I have:
Accupel (Hard), H&N FTT, Eley Wasp, FX, Hobby, Superdome, JSB, AA Field, Marksman (Soft)

Excuses: There is a little 'bunching' of data at times so I expect errors in procedure such that: FX, Hobby and Superdomes could all form a pretty common group. Marksman, AA Field could be another common group.

Cheers, Phil
