IMR 4166 revisiting with 129 grain projectile

[SD GUY]

I see Nozzler is listing load data for 129 grain projectile And listing IMR 4166 as their most accurate propellant Tested.
Anyone been trying IMR 4166 with any of the heavier projectiles?

Have only tried it with 123gr SST, velocity was good but need to work on accuracy fine tuning.,

[6.5 Grendel]

So what is the actual velocitys of the bullet and powder combo?
