Retumbo, H1000, and 4350 keep my attention in 300 and 7mm mags. I tend to shoot moderately heavy for caliber pills to capitalize upon the higher BC and greater impact momentum, so I run 180-220's in 300wm. Never has made much sense to run light and mid weight bullets in magnum cartridges when a 308 or '06 family case can capitalize on 150-165grn pills, just feels like wasted potential.
