I'm actualy in the same situation ... When my friend or me create a game, none of us can find each other ... I dont realy know witch version started that mess ... but I know that when Gamespy were still online we did not have that problem ... I unistalled and reinstalled the game twice nothing changed ... I'm still able to connect to public dedicated server ... but not on simple private game hosted by ourself on the same computer that we play on ... we cannot join or even see each other in the server browser ... I checked the ports and arma 3 is set to all ... maybe I'm wrong (never been a pro in ports and stuff) I'm using a simple router Cisco E1000 with Windows firewall ... every other game that I play still working fine

Should be by the ammo type ... And not alway bigger better take in exemple the 5.7 of the P90 or the mp7 caliber (cant remember the name) they have an insane penetration performance

keep trying to perform with these ... I did well with a mouse after a few hours ... think that the chopper is like a jet in BF3 ... the tail rotor is not suppose to guide while you are over 100 km/h so you have to to turn similar like a plane in BF3 (tryed both so i know what i'm saying ...)

Yeah , the tail rotor won't make you turn on high speed ... that's normal ... reduce speed or move your mouse left or right then try to raise your nose ... that's how you turn at high speed... like a plane in most common games ...
