147gr ELD and Reloader 26 Test

According to the Alliant tech, it’s a tick slower than RL25. Some data suggests it’s actually a bit faster than 25, but Alliant says it’s the formulation. In short, use rl25 starting data, and work up as normal when no better data exists.
This might help some.

Vendors are getting the powder, but backorder fills are eating it all, and it never comes up as in stock.
I picked up 16lbs of rl26 so I could use the same powder for 6.5, .308, 30-06 and 300wm/nm.
Has anyone tried rl26 with Norma or Lapua 6.5cm. what kind of capacity we're you running?

I’m using Lapua brass with 147’s. 46.5 is all I can fit with a drop tube, and my everyday load is 46 gr. 2830 fps out of a 23.5” Broughton.
Got up to 47.2g of 4831sc before I saw slight pressure signs. The gun liked 47g. It hit about 1 MOA @ 100yd higher than my 140g loads that shoot around 2700. I wish I could find RL26 as I need if for the 300.
H4350 is a faster burning powder than RL26. I think most people see pressure signs between the 41.0-42.5gr range with H4350 and speeds south of 2750fps with a 24” barrel. Never tried that combo myself though.
Today, with lack of complete burn rate charts, using Quickload's burn rate properties is about the only option. I've said for 3 yrs we will never see a complete burn rate chart again.
Then, we need to understand specific burn rates change per case size too. We are doing things today with powders that 15 yrs ago we would have been laughed off a range if we divulged the load. Like sticking powders made for magnum cases into a case like the 6.5 creed and it is working.
Do you mean rl16, or 26? Like Jugger said, 26 is much slower, and due to its formulation, it’s going to producequite a bit more velocity.
Reloder 17 will push 2900+ as well.... In a 24" ? 'Murica... Prime brass, Federal 210M, .025" off the lands.
EXACTLY. People using Magnum primers in non-magnum loads, Magnum powders with standard primers!
I wonder who decided to stir the pot. I actually thank them because we are obviously getting fantastic results.
I know with my Prime (Norma) brass, I had to subtract 1-1.5 grains from the powder charge for any book load that used Hornady brass in their testing. Same soup with Lapua.
If you weigh them side by side, the Hornady is 10 grains lighter in average...
Prime average 156.38
Hornady average 147.97
I've found in my experience, a 10 grain difference in brass weight of the same cartridge (after cleaning/trimming/prep) equates to about a 1 grain difference in powder capacity.
Side note, with Hornady brass I had previously weight-sorted them because their weights were mainly in the 145-147 area with a few down to 141 or up to 152. 11 grain spread. So if you work up a load, that difference in weight could contribute to velocity spreads and correlated impact spreads at distance. For killing paper at 100, you're fine.
The Prime brass, I measured 20 randomly picked cases from a ~200 piece lot I processed. Average was 156.38 high was 157.7, low 154.3. 3 grain spread from high to low.

I’m reporting back as I said I would on the other batch of Hornady brass that was not loaded with RL26 or 147eld. This brass was with 42.2gr H4350 and 140eld sized and shoulder bumped with the same die and shot from the same rifle as the RL26 and 147eld. This made it to 14 firings before case head separation appeared. I did start bumping the shoulder back 0.002” less at around the 10th firing.
