I use abyss defiant and or ice breaker. Don't need disrupter if your level 30+... Shooting them by myself the abyss.d and ice.b can take down 4-5 oracles in one clip and 6 icebreaker shots. Any gun with a large clip and leveled is good in my books. Back in the day I used shadow price... Or if your using your hunter, golden gun. Takes down 3-4 oracles depending on if u have the helmet that gives additional golden bullet. I talk with team mates too, when taking down oracles. My buddy would say which oracles their shooting and I would shoot the other. When I'm relic holder, normal have a charge to blast the last oracle or I fly around with the relic to help down the oracles.
