MCH Opener and Rotation Help

[Heatkrieg]

After having read and seen a lot of guides on what the proper MCH opener should be like, I found myself lacking in the amount of damage I should be dealing with my opener. Now, I don't have a parser because I play on the PS4 but I have been keeping track of just how much damage I am doing by looking at my wildfire numbers and comparing them with the ones I have seen online. I currently do this:

Hot shot > HC + RS > Lead Shot > HE+Quick Reload > Split Shot > BFB+Reload > Slug Shot > Reassembled+Wildfire > Clean Shot > Rapid Fire > Ricochet > Split Shot > Gauss Barrel > Slug Shot > Head Graze > Split Shot > Blank > Clean shot > Quick Reload > Slug Shot > Clean Shot

I normally manage to fit in everything above within the wildfire window. The highest wildfire damage I've ever done was 6.2k but I think I was just REALLY lucky with the crits.

Alternatively, I've tried blowing all my cooldowns before lead shot so that it looks somewhat like this:

Hot Shot > HC + RS + HE + B4B > Lead Shot > Quick Reload > Split Shot > Wildfire + Reload > Slug Shot > Reassembled > Clean shot > Rapid Fire > Ricochet > Split Shot > Gauss Barrel > Slug Shot > Head Graze > Split Shot > Blank > Clean shot > Quick Reload > Slug Shot > Clean Shot

Equipment-wise, I'm a i183 MCH with the Ravana weapon, the i190 headpiece, belt and one i190 ring. Everything else is i180.

Your input on any of this is highly appreciated. Thank you .
