Treefork, I agree, IMHO Blowgun's are pretty short range tools (under 20 yds) as accuracy is of prime importance. Although multidarts may be fun to play with, one well placed dart will do the job. Blowgun's can be incredibly effective hunting tools and was one of my favorites until I decided to lie low because of the Kalifornia ban on them. I'm working on getting a permit as we speakOne single well place full size dart is best . The multidart lacks power to each individual dart . A novilty item .
Test them on a piece of wood and you will see they are not delivering the power and penetration needed for a humane dispatch .
