Old load data Winchester action powder (WAP)

[AJC1]

Curious if there is any 357 load data for the old winchester action powder now sold under ramshot silhouette. I called and got load data from the company for 158s which was 8.4-9.2 grains. Now I'm looking for 140 data. I'm interested in old load data sheets and if it's in a particular manual I'll hunt it down and buy it. The new western powders manual obviously doesn't cover it or I wouldn't be looking.

Called ramshot, redirected to hogden and they had nothing. He was so lost he couldn't even find 158 data.... informed me of the link and claimed they published all list data tested. Not quite believing that based on experience.

Your the man thanks. As a curiosity does the 8.4-9.2 load for 158 check.

That 158 data seems to fit better with my observations. 8.8 was ok but got a little sticky chambers at 9.0 and 9.2. I'm going to update my notes.... exellent!!!!

Any chance someone has the letter that said you could use wap data for silhouette until ramshot published data... figure I mise well reach for the stars.
