6 Creedmoor + Slow Powders

[JSH]

There are some old threads that are dated, pre Creedmoor that I didn’t dig back up, but did read.

I see the 4350’s and RL’s brought up but nothing on the slower burning powders. I will admit to being a speed freak, but accuracy trumps speed, more so with the heavies.
Anyone running say H1000 or RL26 with good results?

 

[Twdmar]

Those are going to be too slow to get enough in to get good velocity. Try 4831sc or n160(maybe 165)

RL19, 105, CCI 450 is my wonder load for 6 Creedmoor

I was using IMR4831 (Dupont 1984) in my 6 creed, was not running it too fast 3050 FPS it was consistent and accurate so I ended up buying some of the new IMR4831 at it worked just as well.

My go to was H4350 but I had the old powder decided lets give it a shot and I was pleasantly surprised.

YouTube has a video test with re26. Edk

How was your barrel life?

I pulled that barrel at 1564 rounds, I have another currently at like 1480 and its still shoots good.

My 6cm gas gun LOVES IMR 7828ssc with 105gr amax! Yes my gas block is turned way down.
I don't know why I ever tried it but is the most accurate AR rifle I've ever had. If my stick shift 6cm didn't already shoot H4831SC so good I'd try 7828 in it.

Well, I'll be a monkeys uncle. I was under the assumption that those powders were too slow but it seems there is data out there now.

All mentioned is slower than 4350.

Yeah, a typo, thanks

I shot 48 grs of Retumbo, yes Retumbo , in my standard 243 with a 26” barrel and 105 AMaxes and worked great. Good velocity 3070 and low ES.
Just saying this as the case capacity of the Creedmoor and the 243 Win are quite similar when you factor in a seated bullet in each!

I load 4831sc for mine.

 

[whatwind?]

I load 4831sc for mine.

same here

RL 23 is also very good, drop some vs. 4831sc loads

SW4350 is good also, the slowest of all the 4350's....add some vs H4350

 

[coop2564]

staball for very well and great velocity's.

Rl23 and n160 with dtacs and atips here.
23 being a bit better.
