Here's my options
Here's one for my practical side:
Tikka T3 Lite Stainless Synthetic, 270WSM, topped by a Leupold Vari-XIII Silver locked on 7 or 8X. The rifle is only 6lbs, 3oz. unloaded and unscoped - once fully dressed, it should be just right at around 8lbs. A tack-driver, I would not worry about it letting me down at the moment of truth.
Here's one for my old-fashioned side:
Pre-64 Model 70 in 300 H&H, fitted with a fixed 6X optical device. I would load it with 165-grainers sizzling out of the barrel at a hair over 3,000f/s. I don't think any sheep would scoff at this little setup.
Here's one for my NEXT HUNT!:
Vintage 1920's Jeffery Mauser in .333 Nitro Express, fitted with a nostalgic 2.5X Lyman "Alaskan". In the sleek 3-round magazine, 250-gr jacketed semi-spitzers from Hawk would be waiting to be propelled sheepbound at a good 2,600f/s.
