A 9.3X62. needs to built on a M98! It just fits it's history. I built my custom 9.3X62 with a 1909 Argentine action. If feeds smooth and solid. The majority of my rifles are built on Mauser actions.
If it's all original ( no holes drilled and the original bottom metal) it sounds like a good deal.

I would agree but also might look at having the action heat treated. I had a 1909 done by PacMet and I think it adds strength to the action.
