is a 50 cal. the last time i shot PB i used the 295gr. they performed fine on paper but was not consistent w/ deer. the last 2 years i went back to the knight/barnes hot shot 250 grs. BAM! DEER FALL w/o moving. it seemed to me that i didnt get much (if any) expansion before w/ the PB. i was using 100 gr pyrodex select btw.
