Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

Put an allen set screw in the secondary adjuster.

Once you get it sort of right, if required, use a piece of notebook paper to open the secondaries slightly, fold it over if not enough. Each paper piece roughly .035 thick,is about 3/4 of a turn on a 24 pitch adjuster, 1 full turn on a 32 pitch.
