Dunno if the powder density is correct or how much he's trying to use, but here's a "5% compressed load" for him:

198895

Jfc, he's a determined fool.

There's data online for IMR 4350, 4451, 4831, and 4955. If he's crunching 4895 in there then I hope his face is stronger than that action.

Creedmoor really needs AR2209 or similarly slow burning stuff. Imr4895 is too fast to get decent speeds with 147's.
