Sorry for your bad experience- that really does suck. However, I've never had any issues with 777 other than the "dreaded crud ring". I swab between shots- this takes care of the crud ring, however, I have shot up to 5 or 6 times without swabbing and it still worked okay. Only misfires I've had were when I didn't bother clearing the breech plug hole by popping a primer or two- I noticed it gets clogged up easily, so you need to make sure it's clear every time before you load.
