Bill Norton is the guy that I lifted this from and it seems to make sense as for relative "smack". Essentially, you use the IPSC power factor on rifles. I've played with this a bit and it seems to work. Don't have exact figures (working from memory) but here's how it looks.
Oops - forumula - bullet weight in grains times velocity divided by 1000.
.458 WM - 500 gr bullet x 2000 fps = 1000.
.416 Rem Mag - 400 x 2400 = 960
.375 H&H - 300 x 2500 = 750
.300 Weatherby - 180 x 3100 = 558
.30-06 - 180 x 2700 = 486
.270 - 130 x 3100 = 403
.223 - 55 x 3200 = 176
One has to assume like bullets, but interesting breakdown, huh? I'll post some more when I get my hands on some ballistic tables.
