Bullets, BulletDrop, BulletTraveltime and Replication - Server load and lag [SOLVED]

So what if I wanted to have a lot of bullets without spawning actors but still have a particle trail left behind on every two or three bullets (to prevent them stacking up and becoming an eye sore), how would I move particle trails without spawning actors?
And what if the bullets were slower and i wanted them to be seen?

I’m having issues in my current multiplayer game with the projectiles causing major lag because I have many enemies firing their weapons and spawning 1 projectile every 0.3 seconds
