I just got a used PW 800 convertible that I plan on using to load LNLR for cowboy shooting. My previous loaders both had adjustable shot/powder bars, the PW uses bushings. The load I found that closely replicates the LNLR load calls for 14.7 gr of american select powder. In looking at the Alliant powder bushing chart for PW it shows the lowest charge with American Select is 16.4. How do I determine which bushing will throw the load I want to load? Anyone else load this load on a PW machine that would share their data? The load I am referencing is STS hull, WAA12L gray wad ,14.7 grains american select, 26 grams of #8 shot and a win 209 primer for 976 fps. I also need some info about changing primers because of availability I don't have any winchester 209, I have CCI and Federal primers.
