I am doing some research on my first long range rifle and these are my 2 top of the list calibers because they have readily available ammo (most of the time on the 308) and readily available reloading supplies. My main concern is how the round performs past 1000 yards. I have done research and looked around and from what i can tell they are both great calibers out to 1000 but i haven't found very much about shots past the 1000 yard mark. The longest shot i will take will be maybe a mile because i found a range with a 1 mile target in my area and most of my shooting will be between 700 and 1200 yards. Can someone point me in the right direction of another thread or offer up some advice on which caliber to pick?
The distance you are reaching for you wouldbe best suited going with the 300WM. You will need the speed, and heavy heavy high BC. I love my .308 and the Palma guys can reach out, but it is shedding speed and accuracy at those distances. The 300 is a great round!
At the longer distances when you have to deal with wind issues, the heavier bullets and velocity of the 300wm will shine. Yes, the 300 has more recoil (get a good brake) cost a little more to feed but it will be worth it.
