Follow up. I gave this ammo to my SIL to use in his CZ 550fs and it shot great, however , he too had a ftf, but it fired the next time. Seems that Vortex has a very small shoulder. Worth making a note of. I really like the sharp shoulder of my Whelen Ackley Improved! The Ruger 77 had more ftf as a whole, I don't regret jetting it. My Mod 700 is better suited for what I do with it. My SIL did shoot a 300# hog with it, and penetration/killing was exceptional. She was headed toward him, he dropped down on one knee, and hit her hrough left cheek, through head/neck/down into right ribs. She dropped like a rock!
