I want to set up a gun that is not too heavy but used for hunting. Long Range out to 1,000. I want to go to the range, shoot metal targets out to 1,000 but be able to shoot deer, black bear or elk at long range. That range being 500-600 at deer and out to 400 on elk. I am even more confused at the last thread between the 300wsm and the 300win mag. I know the 300 win mag will shoot the heavier bullets better and longer so I think it edges out the 300wsm for my intended purpose. Anyway, I own a 30.06 and friends are telling me to make it a .280AI. What are your thoughts on these calibers. Will be buying something this week. TIA!
