Crimp setting for M1 Garand ammo?

Where can I find information regarding the degree of crimping necessary (Station 4) for M1 Garand .30-06 cartridges? I'm using once used .30-06 brass, Hornady #3037 BT-FMJ 150 gr bullets, CCI 34 primers and 47gr IMR 4895 Powder. I'm very new at this, and I want to get this exactly right. Thanks

I light roll crimp into the cannelure of the bullet should suffice. Target bullets lack this groove to crimp into, and neck tension alone is sufficient to prevent the bullet from pushing back into the case when fed into the chamber.
