Recovered 338 160gr TTSX pics
I shot these into milk jugs at 25 yards. Recovered weight was 159.4 and 159.6, both expanded to almost exactly .90 x .90, went through 2 jugs and were recovered in the 3rd. Approx velocity was in the 3300fps range.

Great pics, thanks for sharing. I would think a critters skin would let one open up as much as a milk jug 'skin'.

Would really be interesting what would happen at lower impact velocity, any one know what Barnes recommends as min impact velocity for the TTSX?

I do have a 275gr XPB that I shot out of my muzzleloader last fall at about 2000fps that expanded nicely. I would be really interested to see what this same bullet shown in these pictures would do at about 1800fps. Hopefully it would still expand adequately....

Pictures very nicely in focus at such a close range. What camera do you use? I have a Canon S3 that I know about three-quarters of nothing when it comes to using it...

Nice expansion but that is pretty shallow penetration for anything really big. How was accuracy? Did you chrono them or guessing vel.?

Guessing velocity, I was using 1 gallon milk jugs laying on their side, end to end, so penetration was better than if they were setting on their ends the standard way. I actually expected the bullets to exit and was planning to dig them out of the dirt behind them. Guessing at velocity.

Accuracy has been good for me, they are about tied with 95gr SST's for accuracy out of my Tikka T3 243. Both will shoot cloverleaf groups at 100 yard occasionally. My 338WM is not as accurate but 1 to 1.5 inch groups are about the standard, after having tried several different bullets.

Camera is a Canon powershot A620. Here is another picture I took today of an 85grain TSX I shot a doe with 2 years ago and a .451 PBX I shot into mud at 100 yards with my muzzle loader last fall. 85 grain MV was approx 3300fps, doe was about 80 yards out. Muzzle loader MV is guesstimated at 2000fps.

i have wrecked a few does with the 160 grain loading out of a 338 lapua. never found any bullets to compare.

Wow you must have some velocity there! 338 lapua with 160's...holy cow!


Love shooting precision and long range. Big bores too!

I'm impressed all the petals are still there. My experience and observation has been that you start losing petals around 3000 fps. I wonder if they have changed the metal composition? Not sure I want that much expansion though.

I was surprised all the petals remained also, I think it has to do with the larger caliber, the metal is a lot thicker at the base of the petals than something in the 6mm or 7mm range would be. Might also have something to do with shooting them into plain water, versus meat or some more solid medium. They did expand a lot, I would guess that that would be reduced at normal hunting distances which for me would be 100-400 yards.

Fisher 30114-

You inquired about the low impact velocities. This is what I posted on another forum:

It's too bad Barnes can't figure out a way to make their smaller-caliber TSX and TTSX bullets open that well. They claim full depth-of-cavity expansion down to 1600 fps, but I have yet to experience as much on game or test medium.
