When using Norinco ammo "Do not fire the Tavor left handed". The manual says not to do this, and this is why. Norinco loads, at times, will shoot out a foot long flame from the breech. Trust me.We have it on video. I only noticed it once. The video showed way more than once. Think what would happen if it was on the left shoulder. Don't worry about catching a brass in the face. Norinco is cheap ammo but you get what you pay for. I think some rounds were a little to hot. From what I have heard the cheap 800 round cans were reloads. The primers are not crimped so this may be true. Maybe just a rumor.The best ammo I found so far is Hornady VMAX 55 grain ammo just as you did. Accurate and it destroys whatever it hits. But its expensive. I was hitting pumpkins at 300 and 400 yards this fall with all types of ammo. The pumpkins were about 10-14 inch diameter. But Hornady was the most accurate at all distances. First shot everytime it hit what I was shooting at. The Tavor was never meant to be a deadly accurate rifle. I would say 2-3 MOA. But if we are lucky this year we should be able to start tuning these up starting with the trigger group. For me I just like having a non restricted, high quality bullpup, that is kinda a CQB rifle. Put a lar mag in it and head out in the bush. Take cheap ammo. Let it rip. Then switch to the good stuff if you want to hunt or go long range with it. But for me, it was hornady
