Yes, you should be able to use standard rifle data for the Contender, but DO NOT exceed maximum loads. You should NOT use loads designated for Ruger No. 1, as appear in some manuals. In my experience, medium burning rate powders, i.e. 4064, 4320, RL15, etc. seem to work best. You'll lose around 300 fps from rifle barrel length to your 14" barrel; at least that's what my chronograph says. In other words, you can get .30-30 in a carbine ballistics from your 14" Krag.
Good luck! Hope this helps.
