I am looking for the same thing from a 243, two holes. I will try the 100 grain Partition this year.
That's the ticket........
I have two 243's that have killed 14 elk between them. And a few deer and pronghorns. So far any broadside shot on elk have been a pass-thru. Quartering shots will usually stop the bullet before it exits. Most have traveled less than ~30 yds, one did go about 100 yds.
