As much time as it takes*:
MrBorland said:4. Take as much time as you need to make a good shot. It's just you and your gun, so there's no need to rush a shot. Further, don't be afraid to abort the shot if it doesn't all look perfect, if you held too long, or if you suddenly find yourself wondering what you're gonna make for dinner.
As far as marksmanship, you're better off at your next range visit shooting a mere 10 rounds really well than 100 rounds "just ok".
*unless you're formally competing, in which case, you may not have that luxury .
