They are expensive....but extremely accurate with a load tuned well to your gun.
The BC are somewhat inflated as are those of most manufacturers. For example the 195gr .357 DC is advertised as .375 BC I believe. The actual value from shooting this bullet is under .300...but higher than any other ML bullet.
I shot these brand bullets exclusively for 3 years until the 200gr Shockwave hit the market. PR bullets perform very well on game. I never got to shoot a deer with the Keith Nose, but got many with the QT and DC varieties. Most shots at all ranges 20-200 yards were pass-thrus. The only exceptions were a 70 yard and a 170 yard frontal shots. The closer of the two actually flipped the deer end-over-end dead on arrival. I recovered the bullet on the front side of the stomach, flattened and the size of a nickel.
While the company will tell you that you can get 2300 fps out of them, I don't believe it. I personally, and all of the shooters I PERSONALLY know, have never gotten much over 2000 fps without losing accuracy. The soft lead deforms at high velocity, leading to errant bullet flight and sabot non-separation.
If you don't mind the price, go for it!
