When Federal printed the warning Chronos listed, the existing autoloaders where the Browning BAR and Remington 7400. Both, long-throw gas operated systems. The R-1 combines the short throw ARGO gas AND mechanical mechanisms, which to me, suggests less suseptibility to the excess pressures Federal HE pressures. But.....I let someone else prove the theory, thankyou. Seriously, can a moderator contact Benelli about this?
