New Barnes Tac-TX 6.5mm offering

[JuanC]

Has anyone got a chance to shoot them yet? I ordered a few boxes but don?t have any equipment to test with.

Where'd you order your Barnes Grendel ammo from? I usually use SGAmmo.com but didn't see it there.

I had updated the other thread with Barnes response to the min velocity needed for expansion on this bullet.

They told me 1500 fps on vital shoots for min expansion. Said they put the same treatment on it that they use on the LRX bullets.

I just ordered a couple boxes to test out as well. Hopefully they’ll shoot well.

Ran across this.https://shwat.com/barnes-bullets-vor...rendel-review/ Not much detail but he likes them.

That’s good news if they act more like the LRX.

But my testing showed the LRX opening up in the 1800-1900 range. Well below the TTSX, but nowhere near 1500.

Guess it means I’d better get some and melt some gels.

PF, thanks for vid link. Barnes sales guy says velocity from a "16-18-20-ish" barrel is "2600-ish", minimum expansion velocity is 1400 fps, and BC is 0.387. He says it was based on .300 Blackout bullet technology, so that makes sense.

Looking forward to your findings.

With the 120gr TSX on top of CFE223 from several 18" Lilja barrel Grendels, we got up to 2561fps with 30.9gr, but I'm not sure I would load that.

30.0 2435 2424
30.3 2463 2497
30.6 2563
30.9 2561

That big jump from 2463/2497fps to 2563 appeared to be a significant trend line departure.

2480fps average with 30.3gr under the 120gr TSX equates to 2529fps with the 115gr TAC-TX, assuming the proportionality of bearing surface and construction/weight resistance scales from the 120gr TSX to the 115gr TAC-TX.

From a 20" with the 115gr TAC-TX on 30.3gr of CFE223, I would expect around 2574fps +/- 50fps, barrel/primer/brass-dependent.

From a 12.5", I would expect 2360fps +/- 50fps.

Even from a 12.5" at 2360fps, you have more than enough expansion out to 500yds, which is beyond what most people would even shoot with their typical 22"-24" barrel hunting rifles.

With the 12.5" Grendel and the 115gr TAC-TX at 2360fps mv, you have:

100 2151fps 1181 ft-lbs
200 1953fps 974 ft-lbs
225 1905fps 927 ft-lbs

There is still 500fps past that for expansion if their 1400fps floor is accurate. Since they used the metallurgy from the .300 Whisper VOR-TX ammo, I don't doubt them on that.

I just got back from my range with both the new 115 Tac-tx and some Federal 130 bergers down the pipe.
I have some pics but will post them later, my back has been bothering me all day so I'm not moving very fast...

So. Using my RAP mounted in the Mdt Lss-xl for the Grr. And a 4-14x44 PA ffp scope, Arc-2-moa.
Both sets, 4 shots indoors 100 yd, temp idk about 72*.

115 Tac-tx:
2542
2519
2536
2515
Avg 2528 and SD-13. All 4 fed sat from the AR mag using my push-pop feed method.

130 Fed Bergers
2420
2430
2434
2436
Avg 2430, SD-7. First 3 fed sat, the final 4th one I had to wiggle into the chamber, it did not feed ok to start.

Once I figured out I was still 3" high on my zero and re-zeroed, these 2 were POI pretty much the same as my factory 123 sst's and 123 Hdy match (Eldms).

This is a 22" barrel.

From eyeballing the target results with the mgspd off, they both look to be <1"/100, the Bergers maybe even better. So the limiting factor is probably the trigger-puller.

Just ordered some 115's. What powder?

Where did you order then new bullets from?

Grayfox's data is from the factory round with that bullet.

[BluntForceTrauma]

Wanna see pix of this bullet! Not even Barnes has it yet on their website.
