If I'm shooting for fun (read plinking) and burning up a bunch of ammo, without regard for precision accuracy and in a safe place for potential ricochets, then I have a pot full of cheap factory crimped rounds.. I'll also use them at action matches where it's a "lost brass" policy and I can't recover the empties...
If I were reloading for that type of shooting, I'd have a nice Dillon progressive press that I could turn out hundreds at one sitting..
Most of my shooting is of the more precise nature, so loading from a single stage press makes more sense to me... I don't get as many rounds loaded at one time, but I usually will prep a few hundred rounds of brass during my 'down' time (right now it's 34* and snow on the ground) and then it doesn't take much time to drop the powder charges and seat the bullets and I can have a few hundred rounds of more precision quality ready for the range the next day...
In fact, I just finished prepping 100 rounds of brass in the last hour and they are in the tumbler getting the lube off, and ready for storage, until I need them..
If I were buying factory premium ammo, that 100 rounds would have cost me a bundle that I really don't want to give up...as it is today, with the bulk supplies I have on hand, the 100 rounds will cost me $30...
