Load data needed for Blaser 6,5x55 for Varget 130TTSX 129LRX 129SST only.

Post by hunting-ben-hur »

Hi There!
Please post your data, if you do have any experience with the above mentioned components.
I searched and bought several new and up to date books, manuals and searched the internet for days. Unfortunately there are just a few info on load data on this caliber and these bullets. On this I could not find any.
Please do not send other data, only the above mentioned components used.
Thank you very much!
:D

The Barnes site list Reloader 22 as the most accurate powder tested with the 130 TSX. http://www.barnesbullets.com/files/2014 ... Mauser.pdf
But you are correct they have not updated the 6.5x55 data to include the 130 TTSX or 129 LRX an issue I encounter often.

What I do is extrapolate data from other calibers that has data on the bullet I wish to use. In this case the 6.5 Creedmoor.
You will notice that Barnes lists data for the bullets your interested in for the 6.5 Creedmoor.
https://www.barnesbullets.com/files/201 ... edmoor.pdf

You can also see by comparing max loads between the 6.5 Creedmoor and 6.5X55 on Hodgdons' site for any given bullet and powder that the 6.5 Creedmoor can always accept around 1 grain powder more than the 6.5x55. Therefore, using the loads listed for the 6.5 Creedmoor as a reference you can safely work up loads for the 6.5x55.http://www.hodgdonreloading.com/data/rifle

The 6.5x55 operating pressure is 51,000 PSI which is very low for a modern rifle there is much margin in the 6.5X55 for safety due to older rifle metallurgy. Therefore the max loads listed for the 6.5X55 are very conservative 51,000 PSI. The 6.5 Creedmoor for instance operates at 62,000 PSI.

Well first let me say I have no experience with the 6.5x55. But looking at your request I see a couple of possible stumbling blocks. First Barnes doesn't make a 130gr TTSX only the TSX or 127gr LRX. The other is Varget, I could be wrong but I think Varget may be a litttle fast on the burn rate for 129gr bullets in the 6.5x55. Varget would probably be a better choice for the 100-120gr bullets but when going up to the 129gr bullet all the data I see uses powders in the 4350 range and slower. Hopefully others will chime in, please correct me if I'm wrong.

I ran your listed components in QuickLoad substituting the 130gr TTSX for the 127LRX.

38.0gr Varget 84-85% fill, 2600-2650 fps, 47,000-51000psi

Max 55K psi was 39-40grs @ 88-90% fill

I hope this information is helpful and at least a good start on the process. Good Luck :)

Thank you very much, so far.

Your replies are helpful.

There are a few reasons, why I will use Varget:
1. I do have a short barrel 21"
2. It gives slightly more velocity in most cases than other powders, this is good for hunting
3. It works under all temperatures well
4. I can also use it with my 308 Win barrel

You are right, there is a 100 gr and 120 gr TTSX and a 130 TSX.
I do have the following on my shelf for my Blaser R8 Pro Success 6,5x55 SemiWeight Barrel shortened/ threated 21":
Barnes 100 gr TTSX
Barnes 127 gr LRX
Hornady 129 gr SST
Hodgdon Varget
Vit N150

The link I provided to Hodgdon's load data lists the 129 Interlock and Varget. The Interlock bullet is the same construction and shape as the SST. So I consider the load data interchangeable.

The Hodgdon data lists a max load of 37.5 grains of Varget and produces 2,664 FPS from a 24" barrel but at only 46,000 PSI. There is no reason to hold to this pressure level with an R8 but that is the data they provide.

In my personal experience the 123 SST is a superior bullet at the velocities produced by the 6.5X55 producing a wider wound channel and shorter flight distance than the 129 SST.

For a couple of years I was using this combo from my R8.
100grs TTSX is a badass bullet!
43.5grs of N150, Lapua brass, CCI primer, OAL 77.14mm
Sub-MOA groups.

Thank You very much.
Quickload is not a reliable tool, it's a toy, but sometimes helpful. I just tested some 6,5x55 and 308 loads with a chrono speed tester, QL was off.
I do also have RL 19 and RL 22 for the 127 gr LRX.
Varget for 100 gr TTSX.

QL is pretty much accurate, as long as you enter all the relevant data in it.
It is a very useful tool, you just need to know how to use it properly, like any other tool.

Please share what your loads were and what velocities you obtained.

Habe jetzt die Messdaten vom Beschussamt zurück.
Alle extrem zu hoch, ca. 5.000 bar.
Es war jeweils eine Maximalladung knapp unter 3.800 bar (laut QL), nur mit zwei verschiedenen Setztiefen / COAL / L6.
Hab jetzt nachgerechnet und in QL neu kalkuliert (mit Basis der Ladedaten und ermittelten Gasdrücke und Geschwindigkeit V0) und komme bei zwei verschiedenen 6,5x55 Laborierungen mit Reloader 22 und 127 LRX auf folgende Werte

Anfangsgasdruck bei 650 bis 720 bar
Sebertscher Faktor 0,65

Was nun, hat jemand ein gute Idee oder ähnliche Erfahrungen nach einer Gasdruck-/Geschwindigkeitsmessung beim Beschussamt oder DEVA?

Danke!

Swede Loads, hot for commercial action, Blaser R8, CIP pressure (55.000psi) allowed

51,0 grains of RL 22 Barnes 127gr LRX COAL 3,031 in / 77,0 mm Lapua
50,5 grains of RL 22 Barnes 127 gr LRX COAL2.985 in / 75,81 mm Lapua brass measured 58,7 gr H2O

Both about 71.000 to 73.000 psi, measured at the official state authority for pressure measurements (Beschussamt Ulm).

I need to correct input for my Quickload for:
- Sebert Factor
- Starting Gas Pressure

Any idea? Please let me know.

Thank you!!




Here is my request to Barnes (I sent today):

Hi There,

Can you help me on this load. I got your old load data, the book and the new load data from your website. This is all SAAMI.

CIP allowed pressures are much higher and new commercial rifles like mine Blaser R8 can handle such pressure.

I love the 150tsx and 168tsx in .308 Win. and hunted successful with it,
as well as I love the 127lrx in the 6,5 swede.

About 2 years ago, I started to develop loads with the help of tests and quickload.

I have just received back my measurements from the Beschussamt. this is the official state authority for pressure measurements.
all figures (pressure) are much too high.

I believe the data in Quickload are wrong. I put all neede info in the programm: measured brass volume, primer, etc. etc.

Can you help on the data? I need specific data on the LRX bullet for my Quickload, esp.
- Starting pressure
- Sebert Factor

Or other hints that could help me.

I already contacted Engineer Brömel of Quickload and tried to get some info on Barnes TTSX and LRX bullets I've tried, but it seems to me that he does not understand Barnes TTSX and LRX bullets.

Can you help please.

Thanks in advance.

Greetings from Germany,

Marc

Bin zufrieden mit Varget in meine 6,5x55. Aber mit 130gr Accubond bullets, so um die 35 / 36 grains Pulver, MOA. Waidmannsheil, Dom.

P.S. I miss all the great hunting in Germany!! 6,5 is good for Bucks and Boars 8-)
