which powder should I use for 308 tracers

[dgr416]

I am fixing to load a bunch of 308 tracers which powder should I use to ignite them .I have reloader 15,17,19 ,22 .I am pretty sure it has to be a fast powder .They are 150 grain tracers .

Get some Varget...That should do the trick.

I have had good luck lighting tracers in 30-06 with IMR 4895 so it should work fine in 308.
