A 1-10 243 Winchester won't kill stuff. No way.
No point in cutting out the ability to use the 105s though.
These rifles are just a bit too heavy for me to get my wallet out though. 6.8lbs + scope/sling/ammo brings it outside what most mountain hunters want to pack around. Knock off 10-16 ounces and you'll have something to justify the price tag.
