I'll bet you're a fine shot too. I used to do exactly that. I got good quick. Did it for two or three years. At the time I could hit an empty shotgun hull off hand at 25 yards with a 22 pistol.
As per the OP. Guess it pends on your needs and such. I don't shoot 38s much, a thousand will last me a couple years. I'd be worried if it was my main caliber.
