Wondering about how will RL26 would work out as far as potential issues with residue build-up in a suppressor with shorter (~20") barrels. Thinking about building something like a 6.5x47.
Suppressors RL26 with suppressors
- Thread starter Graywolf.260
- Start date
I've been running reloader 15 and 17 in my 6.5X47 with great results. No buildup in the can. Isn't rel 26 a bit slow?

Yeah it's supposed to be slow burning, maybe a little faster than H1000, but people are posting some high velocities with it for a lot of different cartridges from .243 Win to 270 WSM.
You might want to try RL16, it has similar properties to RL26 but it’s a faster powder. You are correct with guys picking up velocity with it but that’s over powders like Retumbo and H1000. I run RL26 in my 6 Comp Match but I’m also pushing 115gr bullets and I have the case capacity to run a slow powder. Not sure the 6.5x47 has the case capacity to see real gains using something like RL26. Now RL26 might be an option with the new 150gr Match King from Sierra in the 6.5x47. I have seen Area 419 working up loads in the 6.5 Creedmoor.
Now o was far as build up in your suppressor, I get some residue in my Ultra 7 but not near as much as when I ran Retumbo. I do run a 25” barrel. Since you have a 20” barrel I would avoid a magnum powder as you more than likely will get unburnt powder collecting in the can.

I tested RL-26 in my 18" 6.5x47, It just didn't have the case capacity to get enough in there.
My results below of RL-26 vs RL-17 (Keep in mind this is an 18 inch tube, so your results may vary)
RL-26 with 140 amax (measured with Magnetospeed)
41.0 = 2463 fps
43.0 = 2561 fps (this was a compressed load, couldn't fit much more in there)
RL-17 with 140 amax
39.0 = 2622 fps
41.0 = 2780 fps
So based on my experience, I would run with RL-17 or 16 in the Lapua.
The RL-26 was awesome in my 6.5-284 though, real good velocity in that.

I would be looking at Varget, RL15, 8208 territory. We had this discussion a couple months ago for the 6.5 Creedmoor. Even 4831Sc and 4350 were to slow to get a full burn in a 20" barrel according to quick load. If I recall correctly 4831SC was 92%. It heated up my can really fast on a 23" barrel.
6 creedmoor, 6 CM, 243 or 243 AI all work great with that slow of powder. The bigger the case the better. The comp match and the AI are the biggest of the ones I listed.
