My .30-06 AI has a 26" Remington sendero/varmint contour barrel on it. Shoots like a dream. With the way I have that rifle rigged, it's right around 10 lbs, and the scope has a BDC reticle that allows for around 800 yards without touching the dial, so it is still very packable for long hikes, and accurate for quick long shots, as long as you know your reticle/load and have your rangefinder handy.
The rifle sits in a B&C Medalist Classic stock with the barrel channel opened up to accept the varmint contour barrel, and has a super lightweight Kahles Helia KX scope and lightweight DNZ 1-piece mount. You get the best of both worlds. You get a light enough rifle to pack, but the heavy 26" barrel for LR performance and accuracy.
