What shank diameter for orgin

[patross79]

Forgive my ignorance on this but I am putting together a rifle on a Bighorn orgin action. I am thinking of doing a shouldered barrel (proof carbon fiber) even though it will take Savage prefits
My question is on ordering the blank, what shank size would I need for a shouldered barrel on a bighorn orgin.
TIA

Origin is small shank, but you can confirm on their website. Plus if you are ordering a prefit for an origin they will know what shank to use.

Savage pre-fits come in 2 shank sizes; Standard (small) Shank / 1.058"-20, Large / 1.120"-20.

You can use either the 1.200" shank diameter or the 1.250" shank diameter. Both work for the small shank diameter threads. The larger diameter simply gets you more shoulder contact on the action face.

Didn't read thoroughly.

Once again, reading is fundamental.

You can not use either large or small shank in the same action threads.

I am aware of the thread forms for the Savage. but...

This member is wanting to use a Proof Carbon barrel which is NOT a pre-fit, which can come with either a 1.200" shank diameter or a 1.25" diameter without threads for a SHOULDERED barrel. The threads are cut by the gunsmith to match the thread form of the action.

Thanks for setting me straight. I'll go delete my comment to avoid any confusion.

Thank you, that's what I was wanting.
Appreciate your help on this.
