Ruger American Ranch 6.5 Grendel feeding issue solution

[Lemonaid]

As suggested I cut one coil off and ran a dummy round through. Results were a bit improved but still bad. Then I cut off the next coil and VIOLA! Works great even with wimpy bolt manipulation. I ended up cutting in total one "Z" off.
Thanks for the great tip. Are there any known down sides of this mod? If not I am doing this to all my Grendel/Arc/PPC mags.
