Bruce,have you tried type C (red) in the dan-inject?
I,have never tried this,it's just a thought.
Whats the chance of pneu-dart making a 11mm dart?
When someone comes up with a "non pressurised" 11mm dart,I'm sure they'd sell a few.
The European pressure darts are ok for controlled situations,but not so safe for wild capture & reaserch.
Most euro guns are 11mm as new.They can be converted,but that leaves the original kit obsolete.
An 11mm pneu-dart would have value & a place in the market,as its the best human safety option for these guns.I think zoos & uni's would pick them up straight away.
