Successful solo Gemsbok Horn primitive barebow hunt...eventually ! Full penetration on this Impala with a 125 gr 2 blade fixed blade broadhead at +_ 120-130 f/sec @ 55-60 pd horn bow. Instinctive shooting [LOTS of practice beforehand !] The arrow went through both lungs and the top of the heart. I've found it dead inside of 25 m. I've waited 4 years for this perfect shot with this unique bow... Thanks again Henk at Aloe Rock hunting -Limpopo !
