For goodness sakes, to convert a 9.3x57 to a 9.3x62 is such a minor conversion that I can do it with my fingernail and the 9.3x62 is a bunch more power regardless of what some have so printed!

Mule Deer,
Your correct of course in that the 98 Mausers are all disigned around the 57 MM cartridge but most have rather long magazine boxes and conversions are extremely simple if you go to the 06 or 9.3 and in many cases no work other than a rebarrel and rechambering is required, sometimes some rail work and lengthening is required..why this is I have no clue....I know the Brno Mod 21 and 22 Mausers have very long boxes and very lengthy throats for thier 8x57 and 7x57, to the point that you can get 8 and 7 x 57 Ackley IMP velocity from them.
