Here's my variation. I happened to have a spare XL360 on hand - don't know why - but it seemed a shame not to try it. The AC10s and PPCs have similar velocity, and I don't think I've ever hit with one and missed the other. I set the weapon groups to match up one of each with each shot. The way things are set up these days, I prefer SRMs to MGs.
That's also a lot of SRM ammo for just one launcher too...that's 34 shots (the final one only fires a couple missiles), whereas you only have 30 shots with the AC10s, which are useful at a much longer range, so will get fired more. As Spheroid noted, you can drop the BAP and go with 2x SRM4 (8 per shot with a smaller spread than a 6, so they hit in a more controlled, central way) you still get 25 shots out of the 200 ammo, and can add another half ton of AC ammo: Slightly more heat, but if something is super close, you won't be firing the PPCs inside the dead zone anyway, and you won't be firing the SRMs at long range, so it's irrelevant
