My daughter will be using the 120gr GMX out of a 6.5 Creedmoor for antelope this weekend. Hopefully I can give a report on how they work when we return.
Good luck and enjoy your time afield with your daughter.
Mine is joinng me on a casual (local) Antelope adventure this weekend albeit using ABLR or ELD-M or NBT. She's brought good luck with the deer, hope the trend continues.
