Thread: Trouble getting 300 Blackout to shoot and cycle subs

I don't think you have a spring strength issue. More of a timing issue due to how slow the carrier is due to gas.
As dogmatix suggested get an adjustable gas block first.
It will allow you to balance individual loads whether subs or full and might well be all you need to resolve the issue.
