Well we are going try if these will work, i will try to get my tokyo marui pro sniper from our customs tomorrow, the ballistic expert that designed the bullet and the barrel believes they will make a grouping of 10 Cm at 40 meters in normal conditions, after the first tests, we might consider producing the bullets via injection, first ones will be CNC though.
The golf ball idea sounds good, but we are not using golf clubs, but barrels, which can allow us to fire non spherical bullets.
Aegs use BBs because they are easy to manufacture in massive amounts, easy to load, and use in gun mechanisms, they can be used in various energy levels, while bullet shaped projectiles and rifling for these bullets need to be calculated for different speeds and masses, etc. Though for normal aegs, yeah those bbs can be good.
