As this MR556A1 is my first HK and AR, I have no experience to draw from so, I was wondering if it was advisable to use steel cased Wolf or Russian ammo in this gun? It would be used primarily for paper punching out to 200 yards. As you probably already know the cost is about roughly 1/2 that of brass cased ammo. Is there a better quality option I should be looking at for a similar steel cased price? Thanks, and as always, you're comments are welcome and appreciated.
