I've heard both ways, yeah they are and no they aren't.
I can tell ya this tho, I've used them to take a lot of game, for a state you can only take ONE deer... But out of a 260 Rem, with an MV of 2950 to 3000 fps , they darn sure work, on anything from 50 yds to 300 yds for me....
Same for me here in PA - from the late 90s to about 2010 that’s pretty much all I used on whitetails and loaned the .260 out to several family members as well - never failed.
