Not used a hornet , but looking at the balistics they are the slowest and shortest range of the c/f's.
I have a fireball . longest kill crow over 500m
longest fox kill 220m
longest rabbit kill 400m
average shots 200-300m
Would not use one for long range rabbits as even chest shot rabbits at 300m will pull the intestines out of the exit hole.
Plus points : Quieter than a .17 rem, less powder burnt and nearly as fast
Bad points : Factory ammo expensive, Can be problematic with feeding unless dedicated fireball action, Rifles for sale rarely, Not many
