I don't even like the .300WM, despite owning one. Mine is not custom, it's a factory R700 5R Milspec 300WM. I can seat 210 and 215 Hybrids inside of mag length of a 700 and still be within 0.015" off the lands with minimal overhang into the case. So, tell me again, how the .300 PRC is relevant? It's not. I could honestly give 2 sh!ts about either one. It's just the fact that Hornady is reheating ballistic leftovers and claiming they're "new and revolutionary". When they're very obviously not.
How is the throat "short and sloppy"? There's a lot of folks out there that might argue with that comment. I personally don't care enough to argue, because I could care less about the .300WM, I'm just curious to know your logic behind that comment.
