Most are made by Uberti, and the quality is very good; they are very nice rifles. Accuracy is great for a pistol cartridge carbine, you can hit anything you reasonably aim at with open sights. As for which loads to use, I would keep it to standard pressures for .45 Colt. While it may be a modern rifle, it's still the old toggle action, and that's not a strong action at all. If you need hot loads, then I recommend one of the Winchester 92's from Rossi; those will take most anything and everything you can throw at them.
