Lock and Load: The Reassembled Machinist Guide

[Myon88]

You can swap it with blank if you want, makes no difference and yes it is very tight there (gauss round comes back barely in time for the 2nd ogcd slot) so I do that myself sometimes.

The second one is a good question and well spotted, you're basically weighing 20 more potency inside wildfire (along with all the other buffs up) against 20 potency outside it along with upgrading the following split shot to a slug. The way it seems to me, upgrading a split to a slug is a 40 potency gain, although since 50% of the time split will proc by itself anyway, I guess you could value it more accurately at 40/2 = 20 potency.

So, 20 potency inside wildfire vs 20+20 potency outside - honestly it's close enough that you could go either way and I don't think it would make a huge difference. Personally I'd opt to just use it inside wildfire.

*If you want to be really nitpicky, using a cooldown like quick reload as soon as it's available is also, in a statistical sense, a very small gain over delaying it one gcd (2.5s), as it gives you a greater chance of ending the fight with one additional use of it in total. Valued at 2.5/15 = 16.7% of the potency value of quick reload.
