I really like their Ultimate tipped conicals but even they are over priced. I have shot the QT version. Its very similar to the Dead Centers in a 45x40 250gr.

They are fairly accurate and do fly pretty flat but nowhere near the BC as listed. Pure or near pure lead also seems to leave the barrel a bit slower in a sabot vs a jacketed bullet of the same weight.

The best price ive found on them is through Cabelas (Extended Range version) if you want to try them. Buying them direct costs more than Barnes or other higher end bullets.
