I used the 7mm 100 gr X when they first came out. It was in my only rifle, a 284 Win. Got 3575 fps with that bullet. It flattened the trajectory before we had rangefinders.
I shot a few coues wt with the bullet. It tended to anchor them requiring a closeup finishing shot.
One time a javelina was facing me from a cave at 100 yds or so. The shot went through the edge of the face through the entire body or so I thought. When I was grinding the meat of the hind leg the grinder suddenly stalled. I discovered the bullet perfectly mushroomed.
Barnes discontinued the 100 gr bullet after a few years of production.
