You should be practicing with what you carry and fresh rounds should go in every time you shoot your last load.
I guess I can agree with that to an extent, but SD ammo is just so expensive when compared to range ammo. My other concern would be if the ballistics are really that different between the SD load and a range load of the same grain. Without a doubt though, I can understand wanting fresh SD rounds in your gun every so often. Like I said, maybe I was just being naive as those points seem to be valid.
