Mule deer
The loads my son used were in a Howa 308 about 8# all up. Fortunately he's 15 an flexible.
I had the same problem with my Whelan as Eileen had with her 08. Getting old is a bitch they don't warn you about. Good to see you solved the problem for her.
Those monometals sure do do a great job, kill out of all proportion to their weight. Deadly is dead whether using 130grain or 220grain.
Give me the 130, gentler and just as deadly. I agree I would use your load on African PG the 140 guys outer edge mono worked on Hartman zebra and Oryx with thru and thru on both.
Enjoy your elk, the closest we get in Oz is the mighty sambar.
All the best to you,Eileen and the family for Christmas from my family.
