Anyway, gold spring, 1 shim, and 1.5 carrier (largest that does not leak) has been working the best, but is a little rough on paint. It has been chopping. I figured since the middle spring won't even work, I can try cutting down the longest spring. I cut it down so it is a little bit longer than the short and shorter than the middle spring to try to get it a little softer on paint. I shot with this spring and the same shim/carrier combo tonight and I chopped a ball. So I tried going down a carrier size because I read that you can really fine tune by going down a carrier while risking bolt stick (info from the level 10 disk). Now, my cut spring, 1 shim, 1.0 carrier is soft enough on paint, but I what will I risk by using a smaller carrier? I let it rest for about 30 minutes and when I shot again it didn't stick at all and I haven't experienced any bolt stick, but I want to check if this is my only option and if there's a problem with it. I feel like I should be able to get the middle spring in there somehow because right now when I do, every other shot is good, but the inbetween shots don't reset fully and are just little half attempts at a shot. Help would be greatly appreciated.
It was once thought that tightening up the carrier was a good way to fine tune the level 10 bolt, but it has since been found that you get more reliable operation by always using the largest carrier that doesn't leak. If you need to really fine tune the operation, then cutting down the longest spring is the best way to do that. Don't forget to remove the shims when checking for carrier leaks and operation. Once you get the mag running smoothly, then add shims to change how far the bolt has to travel before it vents air. Alot of us don't use any shims in our setups and have never had issues. You only need shims if the bolt stops on a breach blockage and won't vent to reset.
If you crank the velocity up, you can't get the red middle spring to work?
If the in between shots don't properly reset, then you need a larger carrier.
Except for the Automag in front, its usually the man behind the equipment that counts.
