Here is what you need Widener's Reloading and Shooting Supply INC if your wanting to see what the rifle will do as far as accuracy goes without handloading .
That "Mexican" ammo is just surplus, and at 200bucks for a 1000rds Im sure its not much and i doubt its brass cased. An it will be dirty. But if your just looking for ammo to blast with give this stuff Widener's Reloading and Shooting Supply INC a try. It will be fairly clean, and its a reloadable brass case. Its also decently accurate at closer distances. So if the day comes you want to reload, you've got a jumpstart on your brass.
The Mexican stuff is brass cased bit for 30 bucks more I can get Independence 9mm which I know my carbine will blow through no problem, so that I might be worth the extra. And I sure will check that out, ive considered reloading but I figured it was really expensive with everything you need for it.
