Friends who know my obsession with firearms often ask my opinion on the subject and I’ve always believed a cartridge like 6.5 Grendel in a suppressed AR platform is the perfect solution. Like the OP stated, low recoil is vital as is remedied with a “light” caliber such a suppressed 6.5 Grendel/6ARC etc can provide. I also think utilizing an AR can have multifaceted benefits with adjustability and fit, but also an illuminated reticle on its lowest magnification solves problems with aligning a hard to find reticle for inexperienced shooters. Third, an AR platform makes a lot of kids imaginations’ soar because most of them are playing first person shooting video games with similar looking guns. All of these details can start a person with as little apprehension with shooting and hunting as possible, while still having enough oomph to do the job effectively.
