Based on the numbers gleaned from the Robert Whitely's post on AccurateShooter, I'd say the 30 ARX is about as likely (or unlikely) as a Grendel might be.
2419 FPS: 28.0 gr. H4198, Nosler 125gr Ballistic Tip Hunting Bullet (2.260″ OAL)
2517 FPS: 29.0 gr. H4198, Nosler 125gr Ballistic Tip Hunting Bullet (2.260″ OAL)
2363 FPS: 28.0 gr. H4198, Sierra 150gr BT Hunting Bullet (2.240″ OAL)
2441 FPS: 29.0 gr. H4198, Sierra 150gr BT Hunting Bullet (2.240″ OAL)
Charges and bullet weights are comparable, so I'd guess they would have very similar bolt thrust forces.
