Hello,

I have a ton of Ramshot TAC and I would like to use in my 45-70. According the burn rate charts it is right in line with what the 45-70 requires for maximum efficiency and compatibility but there isn't any published data listed. A call to Ramshot didn't yield any helpful info as they haven't done any testing with it. Also CFE223. That seems like it might be a tad slow for the 45-70 but "should" work. Would also like to play with these powders in the 338-06.

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
