Ive been shooting the Ultramax 110gr. Sierras. You can get em at Cabelas for like $18.00/20. My groups were very tight with these as well... Ultramax is known to be dirty, but I swab my barrel after every trip anyways. The yote I shot was a headshot at 70yds. and it didnt do very much damage (the whole back of the head was gone, but nothing exploded.). It was DRT though.
Also, the 110's have very littler felt recoil, so you can watch 'em drop in the scope.
