double feeding

[robb2269]

I was playing alot on sat. Now and then my mag was double fedding 2 balls in barrel and I had a few barrel breaks. None in bolt area that I could tell. I saw 2 balls coming out. Could I have short stroked the trigger? My ball detent is good and working properly. If it is being caused by short stroking could I have an ajustment to make with L10? I think always when shooting fast. Any sugestions? :( When I got my x-valve I put the ULT in myself. Maybe I need to tune it better? Any help would be great.

If your detents are ok, then the only way the extra ball could get into the barrel is if the first did not fire. That would require a chuff of some sort which could be a result of short stroking. Use a longer bolt spring. This will make the bolt completely stop on a misfire rather than having enough energy to push the ball into the barrel allowing another to drop into the breach behind it. Hopefully it solves your problems.
