Which blessing would be better on Vraks Mk VII headhunter autogun

[Din511]

currently have no respite and surgical it does a solid job on wiping out specials
but i feel should change no respite with headhunter or deadly accurate blessing
using crit chance talents with two 3+ stamina curios

I personally use Opening Salvo with Headhunter.
Opening Salvo works really well with Vraks. If you don't magdump (which you absolutely should not do with Vraks), it will apply to your every shot.
Deadly Accurate would be a nice alternative to Opening Salvo.

I never use Surgical as there is usually no time to aim even for 1 second. And you don't need Surgical together with Headhunter.
