What a tracer should look like (before spazzing just look).

I guess this could be a flight model issue though as opposed to a bullet model. Maybe the plane just needs to shake more...

You'd be surprised at how little shake a .303 round would have on an being fired from a heavy warbird let alone just hip firing that same machine gun.

SYN_Bliss. Even you must admit that they are too long though.

Actually, in same cases, they may be too short, but I think what they have now is good middle ground.

All rounds arc in reality its due to gravity and friction. As the friction with air slows the round down, gravity changes its trajectory more and more. No fired round ever followed a straight line. ever. period. Across a distance of more than a few hundred yards, this would be apparent, particularly looking down the direction of travel, unless you have a very high muzzle velocity then it would take a greater distance, but still.

Now this is patronizing, but has nothing to do with the discussion. The only point of the arc we care about is the miniscule amount that you'll actually see while a tracer is moving (which funny enough, you can't even see!). If you only see a 5ft section of movement till it disappears from leaving the weapon to out of visual range,.,... that 5ft section (streak of light) following the round will always appear perfectly straight because in the short time frame of the tracer you see (5ft) the trajectory drop is so insignificant it's not even worth mentioning.
