I can’t remember what led me to try TAC, but I have been using it for 223 for about 10 yrs, with the exception of Varget for SMK&STMK.
I have been using TAC experimenting with cast 223 and have run across several threads that point out H4895 / IMR 4895 as preferable. TAC is right next to those 2 in the burn rate tables, and the weights I seem to get best results with also align with thread comments.
Comparison feedback anyone?
Thank You
