Im using the UJ-70 (I think thats the name - .308 pistol) and the shot i took I had no problems; one shot headshot to put down the zombie. However, my next encounter I unloaded a full maagzine into a charging zombie and did no damage what so ever. I had to quickly switch to my axe and it took me 4-5 swings to put him down. Is this a know issue? I left the server and re-entering another now to see if that helps.
