Being quarantined, I watched the old movie "Brotherhood of the Wolf", which is based on the Beast of Gevaudan-Story. So, according to various historians & authors it could be anything from a serial killer (who uses some kind of animal as a cover up) to several ultra-large wolves, to a free roaming hyena or even lion that killed that many people: A 1987 study estimated there had been 610 attacks, resulting in 500 deaths and 49 injuries; 98 of the victims killed were partly eaten.[1] Other sources claim the animal or animals killed between 60 and 100 adults and children and injured more than 30.[1] The beast was reported killed several times before the attacks finally stopped.

If you and your two best friends could travel back in time/parallel universe (ala Chrichtons Timeline) and your job, assigned by the King himself, is to bring safety back to the Margeride Mountains of south-central France , which equipment would you choose? Civilian & portable weapons only, no air support, cars, crew served, grenade launchers, etc. I find that interesting as you have to figure (multiple?) four legged and (multiple?) two legged adversaries in.
As ammo availability is not important here (have to bring all my ammo myself), I would take a suppressed 6.5 Grendel (may the DanielDefense5_V4)with 1-10x scope and thermal scope for night. Although most of the attacks happened in bright daylight, for hunting, I guess a NV/thermal combination google ala DTNVS + ECOTI is a must.
