How to remove slowmotion jaggedness?

Slowmotion is a pretty essential part of my game. I'm using Time.TimeScale = 0.1; to slow down time, although the bullets i'm firing are travelling in a jagged motion now and it seems like the game is almost lagging. I'm not really sure what to do to fix this. The code is pretty basic, so i don't really wanna spam the whole page full of it when all you need to see is one Time.Timescale and a time.deltatime...
