I have been trying to work up some varmint loads with light bullets for my AR 223 with a 7.7 Krieger that is 26". With the 77gr Sierra Match Kings, it likes around 23-24 gr Varget.
With the general thinking being that lighter bullets are best matched with faster powders, what about lighter bullets with slower powders (like Varget or AA2520) with 53-60gr bullets, given I have a longer (26inch) barrel? Or, would I still be better off with faster powders with these light bullets, like H335, TAC, or perhaps H4895?
