gunner, I'm thinking around 3,400 fps with the 130 gr. SSII's. I've seen pictures of complete expansion at 3,300 fps, 3,400 may be pushing their design window. They are tough bullets, we'll see.
The 120 A-Frames are tough bullets, too. I think I can push them near 3,500 fps. with n-570. I'd probably be getting pressure signs with US869 before I reached 3,500; n-570 seems more efficient.
SSII's have a .571 B.C. vs. the A-Frame's .344. So, the 130's should be better way out there. But, I bet those 120's will smack the heck out of a hog...
