Filmmaker,
Getting close to zebra in any setting is not easy.
I applaud you for this work.
Yours truly has taken a zebra at about 40 paces with a double (.450 No2 NE hammer gun) but it was in a shady thorn forest (refer to my Photos) and it took more than a day or two to get within range of a mature stallion.
Credit for this one goes to my Tracker & PH, as always.
I only follow along quietly, anyone could do my part, even me.
Likewise, I am always impressed with how well zebra can remain on their feet after receiving a substantial gunshot wound like these.
I shot the one I mentioned above, spot on the shoulder, as he was quartering toward us, with a 480 grain soft.
He only staggered, then regained his balance and bolted on three legs with his crew, for a few yards then bashing into a tree trunk.
He was possibly dead a second or two prior to that tree?
I enjoyed you film of the .470 / zebra action.
And, will look forward to more when you get a chance to post.
Cheers,
Velo Dog.
