I never shot the original X for the reasons you say, a lotta folks said they couldn't get them to shoot well. From what I understand it was either they did pretty well for some or they did rotten for others...not muchmiddle ground. The one thing that was consistantly saidabout the original X though,is that they were a hammer when did they did shoot well.

Since the original X is pretty muchout of the equation now, the TSX addresses the problems many experienced with the originals. They actually operate at a lower pressure than most jacketed bullets and thus can be driven a tad faster with slightly elevated charges. Less bearing surface due to the grooves facilitates a more consistant opperating pressure than the original, as well as reduced fouling which were the twomain problemswith the original.

The design of the TSX is a near total weight retention anda near totally predictable expansion with the four petals opening as they do. This can allow a lighter bullet weight, driven at a higher speed, doing the same job better than a heavier jacketed bulletwhich isprone to lost mass, and expansion which is at the mercy of what it hits.

IOW, you can crunch a lotta bone and still get through vitals with a lighter, flatter shooting bullet that retains it's weight. Personally I experience quicker kills and a lot less ruined meat with the TSX than I ever did with Partitions, and I can always like flatter trajectories.

I've used them in five different rifles so far andhave never not liked how they shoot. Two 6mm bores, a 25-06, a 30-06, and a 300 RUM. All five shot sub MOA with a little load tinkering. I can like TSX's above the rest.....
