.401 SLR(?) Drawing with Experimental(?) Bullet, WRACo. 1910

#1

From the Buffalo Bill Center of the West, McCracken Research Library digital collection, WRA Co. drawing collection. A drawing without dimensions showing what I believe is a .401 SLR cartridge with a jacketed bullet, with the jacket thinning towards the nose of the bullet and finally opens to expose the lead bullet core. Dated 1910.

Was this ever marketed by Winchester?
