The TSX is good for near-perfect weight retention. From what I have seen or observed in seeing what others have found however, the TTSX appears to be the better bullet even at the not-infrequent expense of some petals. Even the plastic tip in the larger front opening can't overcome the hardness/toughness that copper has versus lead, but it seems to be a significant move in that direction.
I was a big copper fan for a number of years until I was turned off by a number of factors. One of the big complaints leveled against early Xs was the idea that they lost petals and penciled on through. The TTSX seems much more inclined to lose its petals when challenged, yet people seem to be okay with that. Fickle bunch we are, huh?
