You can use unique in your rifle loads too, especially with cast bullets.
I think rifle loads span a wider range of ballistics from essentially pistol loads to 50 BMG. Just thinking about the differences in 22-250, 30-06, 45-70, 416 rigby, the WSMs, the Weatherby mags, 338 Lapua, and 700 Nitro I wouldn't imagine there's a powder out there that covers it all. There are a handful though that cover a class of cartridges well (varmint, medium, large, and african game for example). I'd give IMR 4350 the nod for the most load data covering medium to large game cartridges.
