i did that dumb thing, loaded twice in my Renegade 54. 90 grs pyro ff maxiball and another 90 grs pyro and maxiball. pulled the trigger! well it kicked like a mule on my shoulder. broke the spring in perc lock only damage cept the target had 2 holes within 2" of each other at 50 yds. i learned my lesson of replying to ppl while loading my ML's.[&o]
