Its still available from several manufacturers but its availability in stores is at best sporadic, especially if you are looking for a specific load (like the one your gun is sighted in for) and rather expensive when you do find it. Online places like Natchez, Midway, Buffalo Bore should have good stock of ammo if you plan ahead a little.

But it is a far better cartridge for the handloader, you should go ahead and get the gun and use it as the kick in the butt you need to get into handloading! It is a very easy cartridge to load for and you will not regret ever taking the plunge into handloading...
