Looking for a relatively inexpensive 6.5 Grendel Bullet that I can hand load to break in a build. I was going to use factory ammunition for the first 100 rounds through the new weapon, but it's tough to find right now. So I'm going to have to use hand loads. I have 200 Nosler 125 grain partitions, but I would like to save those for load development and hunting. Thanks in advance...
