i shot them this year in my 30-06 i shot the ballistic silver tips in 168gr. and i wasent pleased with them i shot a large body deer at about 75 yds. a good broad side shot and it diddent expand worth a damn and it was a big ol deer the hole was only the size of a dime it was a good double lung shot so he only went about 30yds with a good blood trail so i guess there ok but i personally think there should have been better expansion they shoot really good and shoot good groups but i just personally wasent happy with the expansion maby it was that 1 shot maby all are like that but i decided to go back the "ol faithful" remington corlocks(sp?) but maby others have had better luck and like i said they did the job fine i just think the could have expanded more
