Guys, I shot a PRS match this last weekend and the wind was howling. Lots of fine dust blowing around. I had 3 failure to fire out of the 120 rounds I fired. Just click and nothing. No marks on the primers so I am assuming the firing pin wasn't even released. I am guessing that the fine dust blowing around got inside the trigger pack? Looking back at page 99 should I flush the trigger pack with brake cleaner? Or try a different approach?
