There is one answer to killing problems with a 243 and that answer is the Nosler Partition. I have seen that many 243 bullets are made a bit too stout to avoid blow up problems at close range. This can lead to inconsistent expansion at medium to long ranges. I have seen this with many bullets including factory bullets.
95 grain Nosler Partitions will solve all of these problems. The copper at the nose is thin and the lead soft. It will expand reliably as they can make the front very soft and rely on the inner belt to control expansion and penetration. We also like the SST but sometimes expansion can be too much at close range. 85-100 grain Nosler Partitions depending on case capacity and don't look back. When the caliber is this small you need excellent bullet action and the Partition will give you that 99% of the time. There is still a problem with the 243 and that is that the flat trajectory can tempt you to make shots after the energy has dipped too low. You can hit them but past 300 yards or a bit more killing power is not that impressive.
