Mike:

If you compare Std length Mauser to a magnum length Winchester or Mk V it would not do cause they are different animals altogether.

The standard action was made for 30-06 length cartridges and though some gunmakers tweak them for larger cases the action still remains a standard length M98.

Now if you wish to compare the lets talk intermediate and magnum length 98, thats fair.... not so?

Double square bridge 98

Intermediate action 98 ( rare cause it wears pure mauser markings and is a 303...... they were actually made specially for Rigby, this one never made it to England and is one of less than a 100 specimens .. it is featured in Speed.

Single square bridge magnum mauser Jeffery 500 ( rare #5 of only 24 )

Standard round ring mauser in 404 by Jeffery, Common variety very popular in Africa with Govt departments of yesteryear.

Rare pre M98 transition action in 257 Rigby by John Rigby: Very few examples exist today
