TIKKA calibers and bolt size. 7SAUM custom build

[T Searles]

Can someone please educate me on Tikka bolts sizes VS Caliber

From my research I find there are 3 bolt face sizes
.384
.473
.540

My project is a custom build of a 7SAUM and I am searching for a donor rifle/action.

If I am correct my build requires the .540 bolt face.

What is the best method to determine all calibers that are an option for me to purchase as a donor action?

Is there a published list of calibers that use the .540 bolt?

Yep magnum boltface
Look for a 300 win mag, 300WSM or 7mm magnum action.
The tikka in long action configuration works well with 7 saum and 180’s and heavier with .180-.200 freebore reamer.
In a short action standard freebore reamer works awesome with 168ish grain bullets.

Thanks SKWERLZ I thought maybe there was a published list. Guess I will start one.

I have been using my Lyman Handbook and looking at cartridge measurements to determine what calibers would work. This is my first build so I'm very "green".

My barrel was set up is for the the longer COAL.

The COAL of the bellow bullets was recommended

My measured Cartridge Overall Lengths (COAL) to lands with these two bullets were as follows:

169gr Hammer Hunter - 3.210"

180 Hornady ELD-M - 3.206"


All advice is welcome!

there’s lists of cartridges required boltface’s, easily found in internet.
Tikka magnum cartridge options are limited anyways because they aren’t a true long action so almost for sure it’s originally chambered in 7 RM or 300 win mag.
There’s a magnum tikka in the for sale area now.
