Beam Particle effect is inconsistent

I am using a beam particle effect for a bullet trail effect for a widdowmaker full auto/sniper rifle type raycast weapon. I have a particle emitter in the first person blueprint that i pass start and end locations to for the raycast and I turn on and off for each shot. In the first person example map it works without fail, but becomes erratic in when it wants to work as intended when playing in my larger, actual play area. For reference, the play area is about three quarters the size of Hemorrhage from halo. I have a sneaking suspicion that it has to do with my map size, but I cannot make any size changes due to the nature of my game. Any solutions?
