Only way to get rid of blowback is to lower your operating pressure and get a bolt w/ orings to help seal up the "firing" chamber. Sorry man no quick, one stop fix here.
the feedneck blowback wont cause a ball to break, it just barely shifts the balls upwards, but it's enough to mess with low pressureized ball stacks. Pulse would definately help.
