Well, I would say that the bow is a decent bow if you want to do some money. It's viable because it's similar to rus bow and longbow , despite its inaccuracy. It can be fixed with +3 rank, which makes the bow a perfect bow : fast, enough accurate to hs someone, hits hard. For my part , I got 150 in archery and 8 PD : it helps.
If you can get a +1 bow for 250k, buy it. I'm currently looking for one too.
@thread about accuracy and velocity:
no, the horn bow got both better speed and accuracy, but less damages. As I said, both are viable, you just have to know how to use them. Also, get a +1, seems you need it ;)
