6.5x55 loads

[HR][/HR]Not one started so figured I would.

Berger 140g Hybrids
51.2g H4831SC
26" 8.5tw Bartlein M24/40
COAL 3.218"
2990fps +/- depending on lot of powder.


Caution, this will not fit a standard 6.5x55 chamber. COAL is too long. You'll need a lot of throat. Barrel started to go after 2400 rounds. Ending COAL after chasing the lands before the barrel burned out was 3.232.

Just out of curiosity, how many firings were you getting on your cases before they wore out??

Glad you made it over from the old site. Not sure most of the other 6.5x55 fans did

I got 6 firings before the brass started dropping primers. It's a hot load for sure. I also anneal every other firing.

I'm running 50.6 gr of H4831 sc under 140 hybrids at 2860fps out of a 24"bartlein.



Im on my 7th firing of the brass with no issues yet. Hoping to get one or two more before the brass goes and ~3000 out of the barrel.



Layton, I'm jealous of 2990!! You must be adding some secret sauce.

How is your muzzle flash? That's a lot of slower burning powder for a short barrel.



I have a 22" Bartlein that will shot both 123 and 140 AMAX's with 48.1 gr of 4831SC. The barrel harmonics are just right with that amount of powder.

I had a good 123 Amax load with a former 6.5x55 I had. It was a CZ 550 Full Stock.



Keep in mind, the barrel was 20.5", which certainly hurt the velocity and the "throat" wasn't too long.



My load was:

Lapua Brass

CCI 200

123 Amax

COAL in my rifle was 2.530" to ogive - measured with Hornady L-N-L (.010" jump)

46.5 grains H4350

Avg MV = 2768 fps



I worked up to 48.0 grains averaging 2850 fps, but the accuracy node was lower and it was showing some slight pressure signs that high. You ought to be able to go way faster than that with a custom tube and a properly set up throat/chamber.

Thanks for the info. I am trying to come up with a load for a factory Win 70 featherweight in 6.5x55 so I am dealing with only a 22" tube. I tried H4350 to start with and didn't have much luck but that was with some different bullets. I will give this a try and see how it goes. Thanks for the info!

KElblys - 6.5x55 GWI

just now fire forming so that load is essentially a std 6.5x55

24" Brux Barrel

46.5 IMR 4350

Wolf Mag Primers

COL 2.92

130 Berger Hybrid

2810 fps

Mild flattening of primer



Honestly a little surprised at the slow speed. I think I will try 2.94 OAL and bump up to 47 gr see what happens.

Was hoping for 3k but barrel could be a little slow. Will be happy with 2900. Not sure half grain can get me 100 fps tho. Maybe 50.



Regards,

DT

Just shot the Vegas Precision Rifle Challenge while fire-forming brass. Rifle shot amazing almost pulled out a top 10.

Velocity sped up to 2925 once barrel was broke in, more where I expected it to be.

Cant wait to work up a load for the GW Improved. Will keep updated. Hoping for 3100fps :)



DT



ETA:

Forgot to mention that when I chrono first time it was -10 at a match in the mtns so that might have skewed data some

yes it sucks working up a load in the winter but you do what you have to lol.

I'm putting together a 6.5X55 improved throated for 140 Berger hybrids. Wondering what loads to start with, and where you are seeing pressures? What powders are working?

Great thread , I'm just starting to reload for my Sako Bavarian Carbine. I'll be watching here for some ideas



What powder would be best for the 20" barrel. I pretty much have all powders for this caliber. Kinda saving my H4350 for my Creedmoor though...

This isn't really the spot for it, but I figured someone who has posted here might have a pair of go/no go gauges for 6.5 x 55 I could borrow. Have a savage action build with a Shilen barrel that's completed and shoots well for the most part, but gets pressure signs earlier and with less powder than anticipated.

It was built and head spaced with a more knowledgeable friend and we used a factory Lapua round for the go and added a piece of electric tape for no go. I would like to borrow a set of gauges if available and check out spacing to see if that's possibly the issue.

I will gladly pay shipping for anyone that can help me out.

Thanks

I just completed some load development for the Swedish Mauser and thought I'd share my results.

This load shot well in a '43 Husqvarna M96 long rifle (29' barrel) and in a '41 Husqvarna M38 short rifle (24' barrel).

Lapua Brass
CCI #200 Primer
Alliant RL-17, 42.1gr (warm load)
Hornady 140gr ELD
Seat to 2.600" base-to-datum with Hornady comparator (~10-15 thousandths off the lands in both rifles)

These rounds will fit in the magazine but you cannot load with stripper clips.

Chronograph results with a Magnetospeed V3:
M96 long rifle: Average 2660 fps, S.D. 8.1 fps
M38 short rifle: Average 2610 fps, S.D. 7.5 fps

RL-17 seems to burn a bit fast for the 6.5x55. I think a slightly slower powder would yield better results. Will update post.

Hey all,
I just picked up a TikkaT3X Hunter stainless fluted in 6.5x55 with their 22.4” barrel. It seems that H4831 or 4831SC might be the best powder. I don’t have any of that but do have Reloder 26. Anyone using RL26?

I may have some data for you... It has been a while since I did much shooting with my 6.5x55 but it seems like I did a little testing with this powder. I will have to check my notes when I get home tonight.
