So we have to start somewhere: Gleaned from this post
HARD: wasp
Silhouette
Meisterkugeln
R10
H&N FTT
Barracuda FT
Cross Premier
SOFT: AAF
JSB
Hobby
Superdome
The order of pellets in the list is not a measure of 'how hard' or 'how soft' so comments are welcome to fine tune the list or add new types. Indeed I always thought AAF were quite hard?
Could it be tested? What if, a big 'if', say 10 pellets were melted into a cube or whatever and a known weight/pointy implement dropped onto/into the cube? The impression left could be measured for depth which would give a comparison between pellets but not a truly scientific measure.
Or would the hardness change due to melting? I can't see why it would other than due to separation of the components ..
Oh the things we do in Lockdown.
