ok so here is a place to report on how the master lot of FWFL lube is working in your application.

in my case my normal load for my super redhawk in 44 rem mag is a 257 gr (429244)swc 3:1 ww/lino, water quenched without the gas check and aa9 powder.
with my last lot of powder, 19.8 grs gave 1340fps. with the current lot 19.8 gave 1380 fps and with FWFL a slight lube star at the muzzle....never happened with any other lube.
gun looks fine with a six shot check of the powder, will report again after accuracy check/ dropping back to about 1340 fps and next full match.....
