I've sweared at them and by them. I've used them in my 270 Win only and only the 130g. I've had them fail to break a mule deers shoulder at 100 yards so it did not penetrate into the vitals. I've had one kill a small doe like the hammer of Thor at 200 yards, but not exit. This year I used it antelope hunting and had complete pass through penetration on a broadside buck at 360 yards. No heavy bone was hit, the top of the heart was gone. He ran about 25 yards before piling up. These are loads traveling 3100fps from the muzzle.
There are those including John Barsness who say they work well at slower speeds so I am going to try the 140 and 160s in my 7x57. Should they work satisfactorly then I'll keep using them.
