How about posting some of those perforated paper plates? 8 inches standing unsupported. I'll show you mine with the Ruger Scout Rifle in .308 Win if you show me yours. LOL.
You can post 25 yards, 50 Yards, 100 yards, or 200 yards for those actual Expert Marksman. Swashbucklers can post results beyond 200 yards, but I may request the opportunity to match or exceed your posting in person at my expense. Of course the attested results shall be posted for all to witness.
