dla,
The great thing about reloading is that you can customize your loads to satisfy your needs. I shoot reduced loads in my 44 magnums probably 90% of the time, but I have the option to shoot full power loads should the need or desire to do so arises. In all honesty, shooting is a fun sport, and I don't understand why anyone would want to shoot full power rounds at rabbits or tin cans. There is much value, however, to using the same handgun for both type of loads.
