To answer the OP, I shoot about every other day, 100 to 250 rounds each day. It depends on the weather and my To-Do-List. I average around 10,000 rounds a year. I reclaim my lead from my sand pit, so my only recurring costs are primers and powder.
The reason I'm telling you all this Lisa is because Ruger also makes the LCR in 22 caliber. It's exactly the same as the 38 special. So.... ya get to practice a whole lot with inexpensive 22's and when ya pick up the 38, it feels and functions exactly the same. My girlfriend is also getting the LCR 22. I recommended that she get the 22 first, but she wanted the 38 first as she knew I would be reloading for us. You would save enough in ammo cost by getting the 22 first so that in a short while you could get the 38 and have two extremely fine guns.
Here are two videos.
The first is an honest in-depth review of the Ruger LCR 38 special. Ruger LCR .38 Special - YouTube
The second is a review of the LCR in both 22 and 38 special and the reason for owning both. Ruger LCR 22 Range Test and Review - YouTube
I hope this helps,
