Chamber on .300 WSM
 

I just got a new Browning X-Bolt in .300 WSM. I have a number of different .30 cal bullets and was going to update my spreadsheet on the gun. I use the Hornady O.A.L. Gauge with the modified case. When I started checking freebore on different bullets, I noticed I could not even get to the Max OAL of 2.860". My other guns have plenty of freebore to set different OAL.

Here are two different links to the same article on "3 inch .300 WSM"
http://www.loaddata.com/articles/PDF...0300%20WSM.pdf

http://www.riflemagazine.com/magazin...19_preview.pdf

In the article it gives chamber drawning and if I read it correctly, from the breech face to the riflings is 2.316". Here is my data from the spreadsheet.
It appears my chamber is out of spec.

MANUFACTURE C.O.A.L. OGIVE
Barnes 150 tsx 2.800 2.163
Barnes 168 tsx 2.770 2.187
Hornady 178 amax 2.777 2.151
Sierra 165 GK 2.638 2.176
Nosler 180 Accu 2.812 2.188

Should I send it back to Browning to bring the chamber to specs?

Is this normal for the .300 WSM to have very little freebore?

Why not send your question to Browning? In the WSMs that I have loaded for, magazine length was the deciding factor in overall length.
