So I just bought a new Stevens long action rifle (.473 bolt face). I am planning to build this for big game hunting which includes elk.

My caliber of choice will be either 284 or 280AI. What I need help is the following:

1/ Trigger
2/ Stock
3/ Which caliber from above ;D

Any Stevens guys out there who has done this before please help me out. I am also looking for any advice on what to stay away from.

Thanks!
