Reloading for the bren gun

Has anyone developed a load for a bren gun? I'm just beginning to reload and I have several hundred Prvi cases to reload but I'm not sure what powder would be appropriate. Also, I will be using 174gr fmj bullets pulled from POF ammo and some pulled 154gr tracer bullets. Thanks for any info.

using sierra match king, 174 gr, I used 38 gr IMR 4064 or IMR 4895.

Thank you. The bren functioned great using 38 gr of IMR 4895 behind the 174 gr bullets. Now to try to figure out a safe load for 154 gr tracers that'll cycle the bren.
