orwapitihunter,
The early AccuBonds that lost tips were also defective in other ways, including not being bonded correctly.
They were traced to one guy on the assembly line who decided to speed up the process, which apparently he though would impress higher-ups. This was a year or so after AB's were introduced, and they'd become so popular, so quickly that demand was sky-high. Nosler caught the problem fairly quickly, but some did make it out of the factory.
I never did run into any, and the AccuBonds I've seen used in calibers from 6.5 to .375 on various kinds of big game in North America and Africa have all worked as advertised--very similarly to Partitions.
