I came into some 164 & found the info above that 125jhp provided .

I used BE data since BE burns faster, I had smokey cases & uped it in .2gr intervals until I got clean cases & finished it up.

I used it in 38/357 with lead boolits, plinking loads .
My biggest concern was stiking a boolit until I learned the "speed" of the powder.
I never went any futher with the load as I did`t know the characteristics of how it would act when crowded.

I kept no notes on my loads ,just wrote the particulars on a peice of tape on the bottom of the can & the can was traded to a collector.

If it smells OK & not clumpy I`d go about it methodically & use it.

More info may chime in , I`ll be enterested to see what does !
