Hornady 7th edition lists 23.5gr as max for Varget, TAC is not listed.I need the max charge data for .223 75 grain HPBT using TAC and Varget. It's probably the same as 77 grain SMKs I have been using, but I figure it doesn't hurt to check when blowing off my face is involved... It's for an AR in case they've got a different section for bolt guns. Thanks!
