I realize that not all surplus tracers will ignite and that mil-spec loads use a specially formulated powder to ensure a high rate of ignition. However, I don't want to add any more powders to my inventory and the only .223-suitable powders I have are the following. Which do you think will result in the highest rate of ignition?
TAC, Viht N-133, Varget, IMR 3031, CFE
