Anyone shooting 150 grn in 300 win mag??

If so what kind of accuracy are you getting at long ranges??
I'm fixing to load some hornady 150 interlock btsp and I'm wondering how far out before they start tumbling

A bullet isn't going to tumble until it is well below the speed of sound…unless you under twist it to start with.
If a 155 Palma bullet is capable to 1000, then so is your bullet.

Cheers.
