Always use the largest carrier that doesn't leak. If you need to slow down the bolt, do it with a heavier spring. Tightening the carrier will induce bolt stick, especially as you reach optimum sensitivity.

When testing your setup, make sure you hold the squeegie against the front of the bolt. If you hold it in front of the bolt and the bolt makes it past 1/4", it will hit hard.
Check your paint by dropping it down your barrel. It should push in with no effort at all. It should almost fall in. If it is tight, that is probably why you are breaking it.
Except for the Automag in front, its usually the man behind the equipment that counts.
