Would you really want to invest that much effort into a round that will be completely obliterated on impact?
I'd be prepared to make saboted finned round that I know I won't get back, but the effort required to make spring loaded fins is more than I would want to invest for a one use projectile.
Using fins (for enhancing accuracy) on a full bore projectile (higher drag) that could only be fired relatively slowly (thus with limited practical aimed range anyway).
The advantage of saboted rounds is that the fins are fixed, velocity is higher, drag is lower.
It's an easier to make round that will go further... no competition for me.
