Depends on how near you are to the target. But most guns in WW2 were pretty innacurate - there was a documentary about the Garand rifle which stated that 80+% of all shots fired missed their target.
Saying that I wouldn't want to try it out
I've personally fired the m1 and it performed wonderfully. The actual problem was the majority of soldiers missed on purpose. They were trained very differently compared to modern soldiers and weren't as desensitised as we are now to killing. But ya over all the game is quite unstable and it loves to randomly crash on me, i'd say avoid this title unless they fix themselves.
