I have used cutting edge for many years years now. Not sure how many but over five years.
I use them in my 300blk, 458 socom, .338 lapua improved,and .375 AM.
They have never tumbled in my experience they seem to do exactly what they say they do. Especially the raptors.
Only ones that haven't shot were the 375gr .375 cal out of my AM the 400gr do just fine. That being said I've been slowly switching to hammers. In my experience they seem to have better on game performance than the lasers. They raptors are amazing but the exit hole is always the size of the bore so on bigger animals with lots of fat you won't always get a good blood trail. But I learned quick just to keep looking as they never go far.
