6mm creedmoor 1/9 twist 27” lilja

Has anyone been able to keep the Berger 105 vld-h stable in a 6mm 9 twist ?

It might work at 10,000 ft ASL

Really???...........

Yep, really!

You could shoot a 12 twist at that altitude.

The reason to ask is that some high BC bullets shoot even when the Greenhill formula for stability shows the losing some coefficient at certain velocities. I shoot SMK 107’s fine with a 9 twist but I’m going to use the gun on varmints this year and don’t want to ice pick them with SMKs. Some bullets tend to be more gyroscopically stable in flight than others.
