First, check if the balls are breaking due to chops or just barrel breaks. You can adjust the level 10 bolt setup to eliminate chops but not barrel breaks. Barrel breaks are affected by paint to barrel match, velocity, weather, brand/type, barrel flaws, etc.
If the gun is firing reliably with the level 10 and there are no leaks but you want a softer push on the ball then put the next longer spring on the bolt and adjust your velocity adjuster up accordingly.

Except for the Automag in front, its usually the man behind the equipment that counts.
