6.5x47L with 130 Accubond
- Thread starter colder
- Start date
I use the same load for the 142 LRAB and the 140 Hybird with no problems and they shoot to the same dope at 1,000 yards,,
the 142 LRAB BC is closer to .600 than the .719 on the box
the 142 LRAB BC is closer to .600 than the .719 on the box
I think the bullets are close enough that load data will be very close,,I like H4350 with the 130s in my 28 inch bbl,with a shorter bbl varget/rl 15 might be better,,
look at 6.5 Creedmoor data and back down 15% and work up and you should be in real good shape,,

colder,
Here's a picture of a powder work up that I did with 129gn ABLRs and H4350, a couple years ago on a nice warm day, with one of my semi-custom Atlas rifles. If I recall correctly, I think I
experienced a little stiff bolt lift, at the one or two upper charge weights.
That lot of ABLRs showed some hope but I never could get them to consistently shoot like Bergers so I gave up on them.

I gave up trying to find Barnes load data and copied the Berger 130 VLD data for the 120 TTSX. No issues so far. Many posts here claim the Berger data is anemic. With H4350 and 130 VLD Berger lists the max at 39.7. Most posters have their "accuracy loads" @ 40-41.5gr. Some are higher. I am not yet so bold. Am going to test up to 40.5 when temps go below 90 degrees here. I have never seen the 15% off of the Creedmoor and work up from there idea. I have wondered about a Creedmoor based load formula. I have a couple of boxes of 130AB's and also some BT's. Would enjoy hearing the results.

FWIW, extrapolation wise, for my accuracy loads, I run 38.8gn H4350 under 140gn Hybrids in my Atlas hunting rifles, which were throated at .163" and 40.3 gn under the same bullets, in my br rifle, which is throated about 40 thousandths shorter and it seems like my brass might outlive me.
...but...I do caution all to start at lower charge weights and work up, watching for pressure signs.
With minimal shoulder set back upon sizing, primers haven't shown me much in the way of pressure signs. The most prevalent indications of pressure that I have seen with this cartridge and therefore the ones that I watch for are stiff bolt lift and 'ejector marks'. I have yet to have significantly loosened a primer pocket.
Good luck with it. I think it's a great cartridge for a multitude of applications.

129 LRAB or 130 AB?
Surprisingly Quickload shows both nosler bullets around the same pressure with Varget and the Berger 2K higher with the same charge. I would have thought that the 130 AB with the longer bearing surface would have had higher pressure.
Varget in 22" or shorter bbls is great in the 6.5x47L. For bbls 22" and longer H4350 has the better burn rate. I run Varget and 130 Bergers with great results.
I have tested LRAB in two different rifles and found that they are very accurate.
When using a Cup&core bullet you can always use data from any other cup&core bullet of the same weight.
Simply because no matter what manuals state as max, a responsible reloader will always reduce the charge weight and work up incrementally watching for pressure signs.
That being said... Quickload estimates....
6.5x47L
48gr H20 capacity.
130gr Accubond.
2.800" coal.
24" bbl.
RL-15 - 37.5gr = 59,900 psi, 2,820 fps.
RL-17 - 40gr = 59,600 psi, 2,867 fps.
Reduce, work up, good luck !
