Here's what i found when I googled "why am I getting first shot drop off":
"abs does 2 things, to the best of my knowhow. it ups the amount of air used to cycle the bolt, as well as the amount of air for the first shot. this prevents first shot drop off and bolt stick. first shot drop off can happen if the bolt doesnt fully cycle on the first shot in a string. so, your abs programing, once you get the upgraded board, will use more air to force the bolt open, and it will increas the amont of air for the first shot to insure it fires without drop off "
Guess I need to check my abs. I know its at some ridiculous high number. Maybe I will reset the Ebisu board to defaults then start from there...
