As with the TSX and the TTSX, I have not used the Accubonds in a .243.......... that cartridge is new ground for me. My wife will be using it from up close to possibly 250 or 300 yards and on coyotes, wolves, deer and speed goats.

I have used the Accubond in .25, .30, ,338, and .375. Have seen them used in pretty much everything else in-between these as well. They work very much like the Partition, in that you usually end up with weight retention of around 65%. Some of the lead washes off during penetration, but I have had retention on a few of closer to 80%. In most cases they have been passthroughs and I did not recover the bullet.

I have shot a moose and a couple of bears at around 25 yards and furthest at 410 yards, plus many in-between. The close shots were complete pass throughs. One was a 510 pound black bear and the Accubond smashed both shoulders and out the other side. Bear dropped like a stone and did not move.

My last moose was taken with a 165 Accubond at 240 yards, double lung, passthrough and didn't go more than ten yards and tipped over.

I think the new TTSX open much quicker and more violently than the TSX from what I have seen so far. Makes sense if you think about it as the tip is driving in like a wedge to initiate expansion on impact.

I shot a wood bison a couple years ago with a TSX at around 80 yards. Complete pass through and broke the off shoulder. The bull lunged forward about 5 yards and then wobbled a bit and tipped over. Things don't get much bigger and he weighed around 2400............ this was a true wild bison, not a farm bison.

I would go ahead and try the TTSX in the .243. I am going to. We can compare notes. I am also going to try the Nosler E-tip in my .257 Weatherby this year and the 250 grain TTSX in my .375 H&H.

We are blessed, there is a fantastic selection of outstanding bullets these days.
