Well, lets see, 38J has 4 50 cals and 1 20mm, pony has 4-6 50 cals, they should be able to do the same thing to a plane if your only using 50's. Trust me, the 50's don't do damage like they should, I'll be lucky if I even hit the pilot in one pass. Bombers I can understand, fighters like a 109 should be down within 20-30 rounds.
They do. Would you like me to post a series of films with 6+ kills using only .50 calibers and still landing with over a 1000 rounds left?
If videos shows what 50's did to a fighter within some hits, then AH has them really wrong if you have to hit someone near dozens of times just to take one plane down.
The reason why it's taking you a lot of rounds to kill something with .50 cals is your own gunnery. It's not the game, I don't know how many times myself or others have to tell you this. You have not provided one single bit of evidence to show how the .50 cals work but if you were to take the time and search the forums, you'll see how this issue has already been addressed and proven that there is nothing wrong with the .50s.
Your problem is:
1) You are not hitting at the convergence point
2) You are not hitting vital areas on the plane (aim for structural weak points (i.e. wing root, tail section), engine, and/or cockpit))
3) You are not firing at a plane at a slight angle when approaching from a six. You will hit with less rounds and do less damage from a pure six position, off set your approach where you come in at an angle to their six position, you'll have more of the fuselage to hit with your rounds, increasing the likelihood of scoring a critical hit.
Once you get over your hubris and realize that problem isn't with the game, you'll see a dramatic improvement in your abilities. If you don't, you'll never improve beyond the level you're already at and you'll continue to make posts with incorrect assertions on how the game is broken.
