[QUOTE="MontanaRifleman, post: 268472, member: 11717"] JWP, I think comparing a 176 SMK to a 130 NP is comparing apples to oranges. The Partition is a balistic brick. I would compare to the 140 AB with a BC of .496 Also, IMHO 2700 fps for a 175 bullet out of a 308 is a little optimistic let's say out of a 24" bbl. I think 2650 is a little more realistic with a 270 pushing a 140 AB @ about 3000 fps, Even at 2700 fps the 270 is pushing an almost equal BC bullet 300 fps faster. It would take a long time for the 308 to catch up. [COLOR=red]Edit: The honady 150 SST 150 has a BC of .525, put that together with a velocity of about 2800-2850 and it will pull away from the 175 SMK[/COLOR] Here's an exerpt from the GS custom bullets site on wound channels...
