I've not done it on .303 cases. I have on .30-06 when I was having problems with neck cracking. You must be very careful not to overheat the brass, particularly the case head, you can significantly weaken it to the point of being dangerous.

I've rarely had case neck splits on .303 military brass, even after 40+ reloads using the Lee collet die. I continue to reload until I see the white line forming circumferentially around the case about 1/2 inch above the head in the web; that's the end of life as a head separation is forming.
