Terminal performance of Partition, Trophy Bonded, & X bullets in 223/5.56?

[Glamdring]

Anyone have any jello or field results of 60 grain Partition or the 55 grain Trophy bonded or 55 grain X bullet from 223?

I am wondering how these premium bullets perform at high impact velocity (7 yards and under) and how they perform out at 200 yards.

Thinking a 18" barrel.

I've used the Trophy Bonded and X bullets, all at fairly close range, less than 50 yards. They both worked well. The X bullet penetrated more. I've used them only from longer barrels so they were probably running a couple hundred more FPS than you will be getting. I would be cautious about using them at 200 yards on anything big enough to require a premium bullet. The 223 is running low on steam at that range.
