Plus 1 on that!

Had an elk run about fifty yards once after a solid hit from a Barnes 7mm 130 grainer.

This family of .308 hornady bullets might just be worth checking out.

And, they are both temperature sensitive. I'll never use them again.

2860fps seems pretty slow - I get 2861fps from a 22" barreled .30-06 with H4350 and 165g MRX (predecessor to the TTSX) and Barnes lists loads in excess of 3000fps with a 24" barrel.

Have not shot anything past 400 with the TTSX but did take a cow elk right at 400 with a 180g MRX from my .300WM. She did a 180 and took a couple steps, turnedup hill and took one or two more, then fell over.

Have yet to recover any TTSX or MRX, from 100g to 180g and no animal has gone more than a few steps. More have dropped at the shot than not and are accurate in every rifkle I've tried them in so they are one of my three most used bullets. (The other two are Nosler AccuBond and North Fork SS.)

I like to keep impact velocity above 2000fps regardless of bullet, even though I think all three that I use most will expand at lower velocities. At your 2860fps M.V. that translates to about 440 yards. At 3000fps M.V. 2000fps will be maintained to just past 500 yards.

I shot a moose at 547 yards with a 150ttsx from my 300wsm. MV was around 3350 and it was quartering towards me. Hit the shoulder and exited behind the ribs on the other side. It was on its feet for a minute or so but only went about 30 yards and down. It worked well and shot 1/4 moa over Superformance powder.

With the all coppers I try to limit my range to where impact velocity is over 2000 fps. I think that one was going around 2350 at impact. Looked like it expanded but it didn't look like it was extreme by any means. It penetrated through at least 4 feet of moose though.

At longer ranges when impact speeds are lower I like the amax. Although I just picked up a box of 6.5 143g eld-x and a box of 308 212g eld-x and I'm excited to see if I can get the to shoot.

Yep, since 2004

I've used Barnes on a good number of animals with good results. Don't believe I have had any walk away either.

As far as TTSX, I shot my 5 pt elk this year at 400 yards. Typical lung shot, he turned and ran. Since he was headed downhill i put the crosshairs above his tail and sent a second one. It hit just to the right of the spine, but put him down. 300 Wby, 180 TTSX. Also dropped a 10 year old Bison at 100 yards. Slid one just below and behind his ear. Dropped like a sack of potatoes. Nice leak hole.



I shot one other 6pt elk with a TSX at 600 yards. Two fairly quick shots, he dropped at the second shot.

I've shot a number of other animals with Barnes X and TTX bullets but no others over 300 yards.

Nor have I. 180TTSX at 3000fps out of my 300wm has always been extremely effective. From muleys to bears, black and grizzly. One shot kills with devastating destruction on the insides.

Liking the looks of that Accubond and Pro Hunter.

I have never had an issue with Accubonds Partitions A frames and hornadies . I love the TSX's but pictures like that really concern me.

What concerns me is that you can't see how silly this "comparison" is.

What in the world is launching a 120grn TTSX @ 2750fps? That's what it would have to be at sea level to get that impact velocity, slower still w/ any altititude. Even my previous model 7 in 7mm-08 w/ a shorty barrel would push 120grn TTSX's out the barrel at 3000fps.

It's no secret that the TTSX's are usually at the limits of reliable expansion at 2k fps. If you're going to stage a test at least make it fair so that the bullet can perform as designed. If it had been launched at 3100+fps such that it's impact velocity was higher then it would have performed much better than this comparison indicates.

That's the very reason Barnes makes light for caliber bullets so that they can be driven fast and have reliable expansion.

And no, I'm not a rabid Barnes fan boy, didn't even shoot one last year, but it's clear that this "comparison" isn't fair.

Thinking that the photo is just showing like impact velocity comparison.

nice photo, but what it does not capture is the rotational damage caused by the Barnes petals. Lead core bullets, as shown, act in tissue like a boat prop fouled with weeds.
The Barnes like a clean prop running in open water.

Although the bullet may be smaller at the end, the hydraulic displacement is greater.

Even from a 7mm08, that TTSX would not be going that slow until 400 yards. Launched from a 7 mag would push that to 500. Even at that range, it would kill, and perhaps more important, at 75 yards it would still punch through bones and not smear off or come apart.

They are all good bullets but note how much premium ammo is loaded today with mono-metal bullets. Very few are shot in lead free zones.

Live game is not wet newsprint which resembles a paunch full of browse. Put a fresh hide on the "in side", layer that newsprint with some fresh big beef bones and see how ugly it can get. Lead cores smear and come apart. Only Barnes, copies of them and Nosler Partitions will keep on tickin'.

For soft skinned game, at 200 yards or less, once you get to 40 caliber, a heavy, hard cast lead bullet works as well as a fancy jacketed small one.

80 gr TTSX from a 25-06 30" bbl starting at 3997 fps



450/400 395 gr starting @2000 fps (100 yds)



Both filled the freezer.

Then the caption on the photo shouldn't be 300yd expansion testing.

David

True statement

Assume he throttled back the load to try and replicate fps at 300 yards.

We've done the same, years ago, with various X bullets (yes X) and found they expanded in media (as noted above) down to 1700 fps as long as bone was hit.

Some may disagree, but IMO the best use of Barnes is to shoot through both shoulders and break the animal down.
Very little meat is lost and tracking becomes a non event.

+1 Yup

It does not matter what the initial velocity is. The point is that these 3 impacted at 2000 fps regardless if they were launched at 2700 fps or 3700 fps.
