+1A 7.62mm NATO projectile with a muzzle velocity of 2650 fps would be exposed to rotor wash for 0.01321 of a second.
I am of the openion it would have very little effect at all.
The hard part would be the buffeting effect on the shooter trying to hold the rifle still.
And shooting with his eyes closed, because of the dust cloud blowing in them.
