Otherwise your best bet is going to be in a 110 kph+ mech with at least 6-8 ML/MPL and a duration reduction. Running around like a bat out of hell kill stealing everyone on the field. I got mine with a BJ-1X pre-PSR while it still had the crazy duration reduction, and since PSR the most kills I've managed is 8 twice once in a Mauler and once in a Dire (pre-skill tree debuff).
Possible with a light laser boat, but you likely won't have the heat efficiency to boat ML or range to snag the last/first couple kills. Timberwolf might be prime for it with the energy debuffs gone though.
Either way getting it in PSR matches is going to be pure luck of timing and being in the right place at the right time.

Also congrats on the headshot achievement!
