I think I have posted pictures and stories about my African hammer experiences.
Left hand Zastava M70 9.3x62
258 shockhammer (I think the name has changed)
65.0gr CFE223 in lapua brass
2585fps
Impalax2, warthogx2, springbok, nyala, sable, zebrax2 waterbuck, oryx
Shortest shot was 40yds and longest shot was 242yds excellent bullet performance with all but the waterbuck down after the first shot.
I am tempted to try their 240gr bullet to get a little more velocity shock and bradding of the shank as it penetrates.
I will add that as with all hollow point monometal bullets, hammers don’t do well if the point gets clogged with brush/wood. They have come out come out with a tipped line of bullets and are currently working on a 9.3 bullet with a tip.
