I have that stability formula saved. The Hornady 155gr .555" bullet has a SG factor of 3.100+, the 155gr Barnes TAC-XP .732" bullet comes in with a SG factor or 1.5-1.6 when plugging in a 1600-1880 velocity. I called Barnes and their sending me a few samples. I'll compare theory with reality later. Thanks.
