You have a higher output tank which is one of the easier ways to achieve bounce.
Use the gold spring on your level 10 if you are using a level 10 bolt.
Use a shorter on-off pin. You can simulate a shorter pin by adding a shim or two between your on-off halves.
The trigger frame is critical as well. Some are better at finding a sweet spot than others. Use shims on the side of the trigger to reduce side to side motion. Any motion other than forward-back movement will reduce your ability to find that sweet spot.
Use an efficient barrel. An efficient barrel will reduce the pressure needed to fire the ball at your desired velocity which in turn increases the pressure differential across the on-off. The higher pressure differential is what causes the reactive effect.
Except for the Automag in front, its usually the man behind the equipment that counts.
