Your description tells me that you have a custom rifle chambered in .300 Weatherby Magnum which was built on a 1903 Springfield action.The weatherby Cartridges did not come into being until the 1940,s and were only available in the Weatherby rifles of that time,It would be har to define a value for you because it is unknown how much work went into this rifle and the components used.If you can locate the gunsmith that made this rifle,i am sure he could tell you the amount spent to create it.

To get a value estimate you need to state the Age, Model, Manufacture and Condition of the rifle.
In like-new, unfired condition, around $1.600- $1,700. Any commemorative firearm drops sharply in value if used. That rifle is the Weatherby Mark V.
