Powder comparison chart? Does such a thing exist?

[surfer365]

I reload using only two powders.... HS6 and Trailboss. I am trying to reload 455 Webley and can't find any load data for either powder. Is there a chart that can compare my powders to the powders that have load data.

The preferred powder is blue dot or unique.

**I know it is a stupid question but I don't want to go buy another powder. I personnal like using trailboss and I have 12lbs of the ####****

Here is one:

and another:

and:

But none seem to show Trail Boss as a powder. It appears to me that 231 load data would work.

As always you need to exercise caution but some powders can be substituted for each other based on burn rate. Do your research starting at:
