Variables apply all the time ingame. IIRC kev ran a test of shooting at pixel distance enemies, and it took an average of 3 shots to score hits.
And I'm sorry, but "shooting a hunting rifle once" has nothing on soldiers of WW2 who spent between 3 and 12 months in basic training, learning every single fine point of the weapon they were issued, and training to hit man sized targets at 600 yards without the aide of scopes. Having also fired all my ww2 era rifles (SMLE, K98k, K31, M24, Mosin Nagant), I can say without a doubt that the FH2 accuracy system is the best we can have ingame. Also, remember, the largest fog distance ingame is around 400m-500m. On average, it is around 300-400m, and normal rifle combat distance in FH2 is anywhere from 30-50m to maybe 200m. IE, this is POINT BLANK for military rifles.
