This paper presents critical current and magnetization data for some multifilamentary Nb{sub 3}Sn wires that have been produced by the internal-tin method. A comparison of magnetization and transport critical current measurements show that filament bridging during heat treatment is a common occurrence leading to effective filament diameters that are sometimes an order of magnitude larger than the geometrical filament size. At present J{sub c}'s (in the non-copper region) greater than 1300 A/mm{sup 2} at 10T have been achieved in some conductors which also exhibit high losses.
