What is your theory on this? Not having a dig. Just curious?
Personally;
I don't see how anything can influence the newtons 3rd law. Projectile gets pushed forward, equal pressure is felt rearward between the projectile and brass neck, then lining of the bore, imparting force on these surrounding contact/sealing points; thus pushing force back trough the rifle into you...
Vacuum or not, even boring a hole into a 20m diameter barrel 50m long, there will still rearward force albeit so dissipated it may/wont be felt but surely this day n age it should be measurable at the butt with an ultra sensitive accelerometer type thingamajig.
Just don't see any room for other scenarios to occur
