You should never be relying on RNG during your opener / WF as a MCH.

Mine goes, 2 Ammo: Hypercharge > Hotshot (Gauss Round) > Split Shot (Reload) > Slug Shot (Flamethrower to OH) > H. Split Shot (Rapid Fire + Wildfire) > Cooldown (Reassemble) > H. Clean Shot (Quick Reload) > H. Slug Shot (Gauss Round) > H. Clean Shot (Ricochet) > Cooldown

I play with 230-240ms and am able to pull (what I believe) decent numbers using the above rotation. If your ping allows you may be able to slot in an extra Split Shot during the WF window.

An amazing resource (and where I got my opener) is Aiuri and Miyuri's ranged guide.
