How to smoothly send a projectile to the player's mouse's position?

I have a custom made muzzle loader script in my game, and I want the bullet projectile to smoothly move to the player's mouse's position in the workspace. Currently, I use velocity,

local hitPos = mouse.Hit.p
						
fireEvent:FireServer(body,fireDamage,fireSpeed,hitPos)

Gun script^

local newFLB = flBall:Clone()
newFLB.Position = body.Position
newFLB.Orientation = body.Orientation
newFLB.Parent = game.Workspace
	
newFLB.Velocity = (hitPos - body.Position).unit * fireSpeed
newFLB.CFrame = CFrame.new(newFLB.Position, hitPos)

Server event^

but it's choppy and broken. I was wondering if there were a better way to send the projectile to their mouse?
