I have! The LEVEROLUTION ammo loaded up the grooves so bad that the bullets actually keyholed, ( hit the paper target side ways). After contact with the company with pictures included they admitted there was a problem with the Micro-Groove Marlins and their ammo. They offered to send more ammo but I declined I did not want to de-copper the barrel after 20-25 shots (their recommendation). Daniel
