With the 171 barnes match last fall I was running 86 grains rl50 for right at 3100 fps from my 24" bbl.. I'd start around 82 grains and walk her up into the 88 grain range for your 160. I don't really recommend the wc872 and 867 powders in the stw but they can often be used. aa 8700 data would be an appropriate approximation for data. I've seen both good and bad from the 50 cal ball powders in this round- I'd hate for you to get a keg and have it puke for you. The stick powders are good and usually have great accuracy.
