Why a 6.5 Grendel in a bolt action?

In Texas we start them young, Belle is 12 years old, 78 lbs, 48" tall, 10 1/2 inch pull.Belle is a Leftie. Mission find an action & round for white tail. That Belle can lift and Point . She enjoys my AK74m- 5.45X39mm, right port ejection causes her to flinch. I prefer a 100 gr to 110 gr Sp Hornaday. for Hill Country whitetail.
Mini Mauser left hand action, 18' bbl . Dream Choice a set of O/U 18 ' BBLs to snap on her O/U shotgun.
For over 50 years my two hunting rifles are, Rem 600-6mm (6mm X 57mm) , 600 Rem. 6.5 Rem Mag with 18" BBls. Never popular, 50 years ahead of there, short action time. Alas there right hand.
Is there a small drop block action for rimless cartridge ?
Warm regards, Mickey
