Cooper 300 win mag
New Member
I have a Cooper timberline 300 win mag, looking for information on a good hunting load for it. I removed the break off the gun. I have only shoot factory ammo out of it. Now with the break off it does not shoot well at all. Looking for some help to start reloading on what powder and what bullet someone has had good success with. The gun is for hunting Elk and Deer. I did reload years ago so I have all the stuff to reload with.
