If I read it right the original question was about FACTORY .44 ammo.
My question is, "Why would you want to shoot factory ammo?" It's terrible expensive. I can't imagine being able to afford enough of the stuff so you could practice enough to be anything like a good shot. And if you reload your own you can load whatever you wish. You can load any kind of bullet, for any purpose, at any velocity, etc. By using factory stuff you're really missing out on a lot!
