Ruger MkIII 22/45 with BAD Remington Thunderbolt .22LR ammo

I shoot a Ruger MkIII 22/45 .22LR pistol with a Ruger scope mount and a BSA reflex sight. While this gun is normally accurate, accuracy depends on good ammo! I purchased two bricks of Remington Thunderbolt and after just 300 rounds I left the gun club in disgust, having lost all accuracy due to wax fouling. By then end of the 300 rounds the gun was keyholing like crazy and shooting a consistent 2 feet right from just 10 yards away! Moral of the story: buy Federal copper-washed bulk ammo in 550 round bricks, it's 10.50 at Wal-Mart and it never suffers this kind of debilitating fouling even after 1100 rounds downrange in an afternoon. (Be kind, this is my first real attempt at video editing and I ad-libbed the narration!)
