duckslayer............. I have not used them and in fact, am wondering the same thing as I just bought my wife a .243 and was thinking about trying them.

I have used TSX and newer TTSX in a number of calibers, from .25 up to .375, and I have seen a bunch more used by hunters I have guided. Can't say that I have experienced the failing to open event others talk about.

I certainly have seen a bunch of complaining about this on the internet, but have not personally experienced it. I imagine there could easily have been some bad lot numbers over the years, most manufacturers have had them.

I do have to agree however with the mention of the Accubond. It is certainly worth considering and one of my favourites. I have never had one fail to do what they were designed to do.
