I managed to pull one out of a buck I shot with a 20 ga. They're Nosler Partitions 260 gr and I think they are .458 cal. This one passed through a hard 1/4'ing away deer through the paunch, liver, lungs and was found in the off leg. Range 30 yds. Ballasticly I think they are pretty close to a 110 gr 2fT7 load.
