RL26 in the 6 Creedmoor ????

[MTlager]

RL 26 is a different animal in some cases . I ran 147 eldm at 2953 with 47.5 grains in 26 inch 6.5 creed barrel with no signs of pressure. RL 16 was next best.

I reviewed some of my earlier comments in this thread and, after playing with both the 6and 6.5x47L, I think RL-26 may work fine in the Creedmoor. And posts by others seem to back that up.
RL-17 worked very well in the x47L, but I ran into pressure 10% below case capacity. Since the Creedmoor is about another 10% on top of that, the much slower RL-26 should be in the ballpark.
It has been well documented elsewhere, and verified by my own experience, that either RL-17 or 26 will also postpone throat erosion significantly.
Those who live by low ES/SD should stick with H4350, so I can get RL-17/26 when I need it.

What are most people shooting with.
H4350
RL16
RL26

I want to shoot the 103 ELD X

So are you saying Reloader 17 can enhance barrel life?

Yes, and so will RL-26. Much of the "total heat content" of the charge is burned well beyond the throat, thereby sparing the throat much of the wear. These are the only two powders available to the U.S. consumer that utilize this technology.
I'm also convinced that the high ES/SD often experienced with RL-17 is a chronograph issue, because I'm not seeing it in vertical spread downrange.

Interesting. So would you say that Viht N550 could also enhance barrel life? It shares some of the same properties as R17 being a high energy double base powder.

NO! They are completely different technologies. I strongly recommend that you read the articles in the archives of this forum about RL-17. There are several.
The test I referred to was posted in the rifleshooter.com forum in April of 2014. The test involved two identical barrels inspected for throat wear every 500rds up to 2000.
H4350 showed twice the erosion at every step.

Would Reloader 22 work in the 6 Creedmoor? If so which bullets?

 

[Alliant Reloading]

I would think Reloder(R) 22 could work ok.
Here is some data we worked up for the Speer 100gr Spitzer BT bullet.

Good old Accurateshooter.com. Just logged back in after years away, finding my way back by ordering a Ruger Precision Rifle in 6mm Creedmoor and looking for information on barrel-friendly powders vs. the 4350 family. It looks like Re17 and Re26 will be just the ticket. Most of my shooting will likely be with Sierra 95 TMKs at modest velocities since my local range here in south central New Mexico only goes to 300 yards. I haven't shot a bughole in many years, and look forward to trying again.

This is the best shooting forum on the web . Im a member on a couple more forums , but for precision shooting and reloading this site is tops . Im about to drop my membership on another forum , because the know it all tacticool invasion is occurring. If someone ask a question people on there will try to be little you . This site is way more mature and professional . Kudos to the founders and maintainers

Thanks Paul.

After reading this I started playing with RL26 on Quickload in my 6mm Creed. It stands head and shoulders above anything else velocity-wise, and at a lower pressure! I guess the temp sensitivity makes it less than the "perfect" powder for this cartridge though. I still have to try a pound of it for myself.

Would you mind posting a starting load for a 110smk? I don't have QL, but am curious about expected velocity.

I currently use RL17/110gSMK/Hornady brass/BR2. I have a whopping 70 rounds on the barrel.

Did you add 6 Creedmoor to your quickload program or was it there? My understanding was that it and Superformance powder are missing which is what has kept me from buying it. Would like to make the purchase though.

The 6mm Creedmore was on the newest update disc . If you buy Quickload new now, I would make sure he knows you want it in the cartridge selection. He’ll hook you up.

The new 110 smk is not in QL, and it is tough to emulate that bullet in the program.

Thanks I'll do that. Still missing Superformance? It and RL26 are most interesting to me for the 6 Creedmoor. Both should be extremely effecient and yield higher speeds with lower pressure if the temperature doesn't cause too big a variable. Hornady's published data for Superformance in the 6 Creedmoor looks promising I'd like to play with both it and RL26 to see how they work and how temperature effects both. I've used Superformance in a 243 and it has worked exceptionally well.

Reading this post got my curiosity stirred up, so I thought I would try some different powders in a new 6 Creed build I have just to see what kind of velocities I could get with the 115 Berger hunting VLD. Has a Krieger HV 8 twist .237 29 inches long with 145 freebore on a P1000 action. Plan on using it for a long range deer wacker so have no interest in the 105 gr bullets. Started out with RL 16 and after 80 rounds on barrel 40.8 gr of 16 went 3108, 3104, 3110, then 41.0 was 3129,3126,3131 with magneto. Accuracy good at 1000 yards. Switched to RL 26 only shooting 2 of each just to get a velocity spread idea and not concerned about accuracy yet, 45 gr went 3173, 3188, 45.2= 3196 3196 and 45.3=3198 and 3197. Little under 3/8 each at 100. Not great. 45 gr of H1000 only went 3011, and with a long drop tube got 46 gr to 3083. The eye opener was IMR 7828. I worked up to 44.0 for 3176 then 44.3 produced 3213 and 3208. It was hot out and saw no signs of pressure. Will do some load tuning with the 26 at 1000 yd to see if it shoots better than the 16 just for the sake of using a slower powder to save on barrel life. This thing shoots very flat and will be interesting to see how it does on steel out to 1600 plus.

I shoot a 6SLR. Almost the same dimensions but .060 longer body, I think. Been running 7828 for quite some time running 108s around 3125. Got onto RL 26 last year.... wow. 108s no prob at 3250... great sd. Recently been working with 115s at almost the same speed. Ran a multi yard steel match in Ely NV a while back. Didn't pay attention to ammo... tested ammo temp at over 90 degrees before I put it in the shade. Dope didn't change.... I was very happy with the performance.

as usual... sneak up on your load and don't worry if your barrel has other likes or results.
