Hey, new to Savage and building my first rifle. I've got a 116/16 Trophy Hunter in 308 and plan on buying a Boyd's Stock Thumbhole Featherweight stock. But I've got a few questions.

1. Is 308 always a 16 and not a 116? All the info on the box and manual say 116/16 and never specifies, but I need to know for the stock requirements.
2. Am I correct that the 16 is the short action and not the long action?
3. Does anyone know the Savage part numbers for a metal magazine box and metal trigger guard?
4. I plan to do pillar bedding through a local gun smith. Anything I'd need to get first before he can fit the barrel outside a new magazine and trigger guard?

As I said, it's my first time swapping out a stock. Anything in particular I need to be aware of or typical trouble shooting issues with this kind of Savage?

Thanks for the help!
