I think it's worth the $350.00, sight unseen. The 9.3 will make a good hog rifle for your neck of the woods.
A few years ago I picked up a 9.3x57 very cheap since no one knew anything about it, including me. And when I stopped back in that same gun store they had the same rifle in 9.3X 62, so I grabbed that one too. Later I was able to find a large supply of brass, speer bullets and dies on an auction, that surprisingly no one would bid on. Like someone else mentioned it's more better than the .35 Whelen Improved.
I mentioned the round to an old timer at work one day, thinking I would impress him, and he comes back with "we used to use it on cape buffalo all the time. It's a very popular caliber in the south of Africa." He served with an NGO in Africa for 20 years.
See keep your eyes peeled on the auction sites for a while and you may come up with a good deal on reloading supplies. The cartridge is pretty much under the radar still, I think.
Let's see some pix!!!
