Here's my reply to this same announcement on another forum:
First, this is very exciting news for long range hunters who prefer a bonded bullet. The original Accubonds are good bullets, but with their relatively short noses and essentially non-existing boat tails, they just didn't have the BC's for long range. However these new LR Accubonds look much better designed for BC.
Having said that, I have to apply the sanity check to the advertised BC's. Consider the G7 form factor (noted as i7 and explained in more detail here: http://02b0516.netsolhost.com/blog1/...analysis-tool/
The form factor is basically the component of BC that describes a bullets drag in relation to a standard, lower is better.
The lowest form factor (lowest drag) bullets I've ever tested are in the neighborhood of 0.89. On average, Berger VLD's have form factors in the .92-.95 range which is quite good and results in high BC's.
The G7 BC's cited in the announcement imply the G7 form factors listed below. As you can see, some of them are quite low. I tend to question any claims that imply form factors below .90. After all, of the 100's of bullets I've tested, there's only been 4 or 5 that have actually had form factors below .90 and those have been radical designs, often requiring non-standard twists.

I haven't tested these bullets yet, so I can't say for sure if the claimed BC's are accurate or not. For now I'll say congrats to Nosler on offering a bonded bullet geared more for LR hunters. I'll report back when I've done some BC testing.
