I agree with Jeff. Don't trust the inexpensive HP bullets to be effective. They may expand but not penetrate or penetrate but not expand.
Premium bullets are available as reloading components if you decide to go that route.
Personally, I buy my defense ammo. I'll replicate it on my reloading bench for practice.
