408 Load data for 385gn bullets

[DuaneTuros]

I am in the final stages of building a 408 CheyTac and need some advice on starting loads. I will be using Retumbo and RL25 with Wolf Lg rifle Magnum primers, Jamison Brass and Lehigh 385gn pills.
The rifle is built with a Lawton 8000 barreled rcvr. McreesPrecision stock and a NightForce 5.5-22 50mm scope.

TIA

Wow , sounds like a nice rifle. Are you sure the Airforce is tough enough to shoot that beast?

Go to your room Greg. I hope it's cold in 29.

Thanks for the help. I am still waiting for the primers, they just shipped today so I hope to be shooting by next weekend.
