I have a .25 auto that was my granddads. It is small enough to fit in the palm of my hand and I was thinking about using it for my concealed carry. I want something that will expand very well. I don't plan on using it for anything but protection.... but if I were actually in the situation to protect myself or family want a bullet that will perform well. I am not planning on reloading ammo for it... but just want some good expanding factory ammo. Any ideas?
