Mauser action should be longer than the traditional short action.
To find out which Mauser action you have, i'd check out the measurements given here
www.hoosiergunworks.com
You will need a pair of calipers to measure how thick your receiver is, and a tape measure to measure the distance between screw holes in the trigger guard and bottom metal.
Boyds stocks for Mausers do not come inletted for the bolt handle, as there is no standardized bend (if there is a bend).
Go to Boyds website, they have instructional videos on how to figure your length of pull, and such.
