They are my start bullet generally, until I can get time to sit down to work my TSX into the formula. I used to think of them as an ok bullet mostly and a bit frangible if anything. I loaded for my buddy for a number of years, 165 in 06, then he shot a buck where the bullet NEVER expanded at all, through both lungs and they killed that buck 3 weeks later with a neck shot.... that original shot hit a rib going in and out.... we moved him to TSX right away.
I didn't have time to mess with a lot of load work last fall and shot 160s in my 7x300.... talk about wild performance. Couple of head shots did fine, then we had a couple that penciled through....the final straw was that about a 50 pound hog stopped the complete bullet lengthwise at a bit over 250 yards.... to much uncertainty about what it will do IMHO. But then thats typical of Cup and Core.
