Depends. Under 200 yards the flat based bullets make bug holes. 55g Vmax, Nosler, Berger SMK from 50-60g. 25-26g of CFE will rock. Past 200 yards the heavies shine. 69 or 77g SMK and the same weight Hornady BTHPs are superb. 23-24g of CFE. I do like CFE but I get better velocity and accuracy with Ramshot TAC. I'm now experimenting with Benchmark, XBR8208. Also like Re15 and Varget bit TAC flows like water in my powder measure.
