I hope you don’t mind me copying my observations posted elsewhere, see below. I had great results on two elk with the CX before I moved on from that rifle. N=2, so take it for what it’s worth. In terms of accuracy from CX handloads, I had sub MOA accuracy with a 300 WSM Xbolt and a 30-06 Sako 90. I had right at MOA accuracy with a 270 Model 70. With those three rifles, the Outfitter factory loads shot just about as well as well as my CX handloads. And then there was a 30-06 Weatherby Vanguard- worst groups of my shooting life from Outfitter factory loads. In general, you will know from the range if they work accuracy wise. And I’ve been impressed with terminal performance.
As posted elsewhere:
I've loaded the .308 caliber 180gr CX in my 300 WSM X-Bolt since the release of the CX. …This has shot MOA at a couple different powder charges with the H4350… Bullets I have recovered mushroom as advertised by Hornady. Last fall I shot a cow elk at 190 yards. She stepped forward as I pulled the trigger and my quartering away shot turned into a hip shot. The CX obliterated the hip/pelvis, carried on into the abdomen through to the lungs. She went about 20 yards and was found stone dead. I'm grateful I had that kind of penetration because I messed up…The next year I shot a young spike bull at 215 yards, quartering away. The bullet entered at the right posterior ribs, nearly split the liver in half (see photo- you can also see that it had enough hydrostatic force to burst the liver in places), tore through the lung(s), collapsing them and damaging major vessels, leading to a significant amount of blood in the thoracic cavity. I was able to recover it because it continued on to fracture the off-side humerus and dislocate the off-side shoulder. I found it under the skin perfectly mushroomed (see photo). Impact velocity was around 2600 FPS. The elk crow hopped twice, ran about 15 yards, and crashed onto his side, where he stayed down.
