bullets, brass, ammo for 351 Win SL

We are now supplying bullets, brass, and ammo for the model 1907  351 Winchester self loading rifles.   Our bullet is a 180 grain round nose gas check designed for the 351 wsl cartridge.  We are sizing these to .352" diameter.   Our brass is being made from 223 Rem so lacks the semi rim of the original cartridge but functions without issue in our model 1907 Winchester rifle.  The model 1907 is a blow back action much like semi auto 22 RF rifles. It also has a fixed ejector so ejects the brass made from 223 Rem without any issues.  In my opinion ejection is improved because with the original semi rimed brass these rifles eject  very energetically making brass hard to find.  With the reformed 223 Rem cases eject with less vigor and consistently just a few feet to the right of the shooter making brass much easier to find. 
Our ammo uses the reformed 223 brass and is loaded with our new 180 grain round nose gas checked bullet to an average velocity of about 1400 fps..
Long live the 351 !
