So I have loaded for 7-08 and 308 for several years now. I have a couple pounds of Ramshot TAC and it is phenomenal in my 308. This has made me wonder if TAC would be applicable for my 7-08? Western powers does not list as an option and neither does Hodgon, so I may running in the wrong direction. Dr. Mike, is there any quickload data for 7-08 with Ramshot TAC using the Barnes 120gr TTSX and Nosler ballistic tip 120 gr?
I can use CCI BR2 primer or WLR primer.
If I am way off base here folks, just tell me.

You didn't tell me your barrel length, so I went with 24 inch. The charge won't change, however.
 
I have 22 inch tube. Thank you so much. Why do you think that Western powders does not list TAC as an option for 7-08?
