I just came into a Tikka Lite in 223 Remington and now am loading for 2 of the rifles at the same time. Instead of tumbling brass for one rifle and then do the same for the brass for the other rifle I would like to limp them together and cut down tumbling time.

Do you guys color-code mark brass? Where do you mark the brass? Will tumbling remove marker color on brass?

I know I have a box of Black Hills 223 Rem loaded with 50gr Vmax and could use that exclusively for one of the 223 Rem but I have plenty of Winchester brass so might as well use them and this is why I am asking...
