We are trying the speer 85 gr boat tail in our 243's this year and we're liking them. It's what we shot the antelope with and they have performed very well. My boy shot his at 199 yards on a 1/4ing away shot and it punched through from mid way rib to opposite shoulder shot. It took out all the good stuff and crushed the shoulder from in side,it did not come out. My goat was way closer at 140 yards and only a bit facing away shot. I slipped it just behind the shoulder and it came out just behind the other shoulder taking out the knee on the way then in to the dirt. there moving right a long at 3300 fps.We are also using a 100 grain speer boat tail in the 25/06 going very fast and it speeded out to 400+ and flattened my daughter-in-laws buck in its tracks.
