New Barnes Tac-TX 6.5mm offering - LRRPF52 - 02-07-2020 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. New Barnes Tac-TX 6.5mm offering - grayfox - 02-09-2020 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? New Barnes Tac-TX 6.5mm offering - A5BLASTER - 02-09-2020 White Smoke Wrote: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. New Barnes Tac-TX 6.5mm offering - BluntForceTrauma - 02-09-2020 Wanna see pix of this bullet! Not even Barnes has it yet on their website. New Barnes Tac-TX 6.5mm offering - grayfox - 02-09-2020 here you go. I didn't notice this before on the box, but they have I guess 1 6.5 and 2 - 300 BO! New Barnes Tac-TX 6.5mm offering - grayfox - 02-09-2020 1 more. [ATTACH=CONFIG]15444[/ATTACH] New Barnes Tac-TX 6.5mm offering - White Smoke - 02-09-2020 Ordered them from a local gun store. I also talked to Ryan at Barnes last week. He said they had load info there at Barnes, but I didn't get it from him then. I sent them an email today asking for the load data. I will let you know what it is when I get it. I suspect that it's about the same as for the 120 TTSX, but just a bit hotter. Just speculating now until I hear from Ryan, but I will probably make up seven loads of 4-rounds each using H335, RL15 and IMR 8028 XBR. I'll probably hear from them tomorrow and will post it here. New Barnes Tac-TX 6.5mm offering - grayfox - 02-09-2020 I haven't pulled one apart (kinda expensive LOL!) but w/ a magnifying glass I see the first part of the first band right above the case. Thought at first it might have been a cannelure but no serrations in view - so, relief band.

Do they have a boat tail? Ask your LGS where he got them from... Load data probably something somewhere 1/2 way between the 100 gr ttsx and 120 gr...

I will ask them where they got them when I pick them up later in the week. May even be here tomorrow. New Barnes Tac-TX 6.5mm offering - White Smoke - 02-11-2020 Just got the info for the 115 grain TAC-TX BT from Chase at Barnes. The bullet has a BC of .387 and an OAL of 2.185". The four powders I have on hand are: IMR 8208 XBR 24.4 (2264) to 27.1c (2498) RL 15 24.3 (2279) to 27.0c (2511) H335 25.2 (2279) to 28.0c (2519) CFE 223* 27.5 (2350) to 31.0c (2660) but I do have info on A-2460, X-Terminator, PP 1200-R and Benchmark if anyone wants it.

What barrel length did they say that data was from? 24,22,20,18,16? I'm thinking 18 or 20 inch. New Barnes Tac-TX 6.5mm offering - White Smoke - 02-11-2020 24". When I get the bullets, I'll make up six strings of four bullets each at half-grain increments with all four powders I have. There goes the entire 100 round supply! :-) New Barnes Tac-TX 6.5mm offering - grayfox - 02-12-2020 Good data. Thanks! Now to find some bullets out there! New Barnes Tac-TX 6.5mm offering - BluntForceTrauma - 02-12-2020 GF, thanks much for pix. Does the black tip on this 115 TAC-TX seem slightly larger than the blue tip on the 100 TTSX? If so, that's a good thing. Should lower the expansion velocity. Also -- just eyeballing it -- looks like Barnes is loading their 115 TAC-TX to a shorter-than-necessary Cartridge Overall Length (COL). New Barnes Tac-TX 6.5mm offering - A5BLASTER - 02-12-2020 grayfox Wrote:1 more. I can see the first band just at the case mouth. Hmmmm I bet this bullet is very close length wise too the 100 grain ttsx and tac-tx. I bet we can make this bullet scream in a handload. I'm calling Barnes now and see if they can give me a lead to order 400 of them. New Barnes Tac-TX 6.5mm offering - grayfox - 02-12-2020 Save a couple (boxes) for me!!! The tip seems to be a bit larger but I didn't do a side by side yet. Will do that shortly.

These are the same powder charges as the 120 data on the Barnes website, seating depth is different. https://www.barnesbullets.com/wp-content/uploads/2017/07/6.5GrendelForWeb.pdf It’s an interesting bullet. |
