I am just wondering if there is a good reliable procedure how to go about using the burn rate charts along with published data to work up a load with powder that has a proper burn rate but no data provided yet.
Thanks,Todd
Todd, I do it all the time.
A couple of basic caveats:
-Reference burn rate charts from several sources.
-Make sure the burn rate charts you reference are for the age of the powder you want to use.
-As John mentioned, be conservative when it comes to spherical powders in big volume cases.
Another approach that I use quite often is to establish a lower end charge weight with a 'published data' powder. Then, with the 'no data' powder (of similar burn rate to the known powder charge you've weighed), just use that measure setting. The volume and weight will change but it's surprising how close this gets you with a 'no data' powder.
Good shootin' -Al
