348 gr Aerotip and 115 grs of 777 at 45 yds = no exit with a chest hit and nothing found bigger than maybe 20 grs. The deer only ran about 35 yds. so I guess it did its job but I think there are many better bullets out there. If you use them I would listen to some of the other comments and keep the powder under 100 grs. Just my opinion.
