If you need powerful and quiet, get a Benjamin Marauder .25 caliber.
Call them in, and shoot them at 50 yards or less.
"Shoot him in the head, Poot!"
THIS, a 25 cal will handle yotes with a well placed shot. I killed one at 55 yards with my mod 25, he went right down. He wouldn't have went down any fast if hit with a 308
