Yes, both first and second hand.

I use the 200gr. FTX's in a .356 Winchester. They cluster into tiny (for me) groups at the ranges I've shot. Haven't done terribly long distance but this rifle is intended to be a 'Close Quarters Hog Rifle' (CQHR for the ininitiated). I have not yet taken any game but I expect they'll perform.

Two other second hand experiences...
A fella chased hogs with us one year, used a .30WCF with FTX's. Hit a hog twice and put him down for good. Both bullets were recovered and a fella could have cleaned them off and used them in a magazine ad they were so perfectly mushroomed.

My brother loaded up a .357 in an NEF Handi to be used by a young man (~12, I think) to take his first hog. He did and it worked just fine.

I would not hesitate to use them against deer or hogs.

Hope this helps.
