RL26 in the 6 Creedmoor ????

[hawkeyeshoooer]

Omg, I have been looking for this info for awhile now, thanks for all the information guys.

Waiting on my PRS gun to get rebareled right now. It’s a 6 creedmoor with 27” Brux barrel and the new barrel will be the same. I got around 1700 shots out of this barrel running RL26 the whole time. Never have had a problem with temperature swings effecting the velocity and I shot in cold and very hot conditions. I was pushing Berger 105 hybrids at 3150. Didn’t exactly give me the barrel life I was hopping for but did seem to last a little longer than what I hear from other guys running the 6 creed at 3150.

I found it the same for 6.5-47L. Accuracy, ES and SD were very good but just ran out of room in the case. As for the 6 Creedmoor I settled on 42 grains RL16 with 105 Hybrids. You should drop off that a bit and work up to be safe.

Do you remember your speeds and with what barrel maker and how long? Also throat length too, if possible. Basically everything. HaHa Thanks. I'm almost to the same charge on a ladder test.

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.
: )

Was it really that much difference over RL-16 ? And is RL-26 heat insensitive also? Thanks

What charge or RL-26 for the speed of 3150fps using Bergers 105gr Hybrid ? And what primer too please? Also who's brass with small or large primers? Thanks

My barrel was hitting 3150 with 42 gr H4350 after break-in but has around 1,300 rounds now. Last time I had the Magnetospeed out (500 rounds ago) I was seeing 3064 with that same load. Switching over to RL16 got me back to just over 3,100. The barrel is 26" Bartlein 5R with 8T. It was chambered by Accurate Ordinance and I am probably one of the few that never asked them about freebore. They knew it would get a diet of nothing but 105 Hybrids.
BTW, I hope you find as wide a node with RL16 as I. It came in at 41.4 and stayed there all the way up to 42.4 but I will caution you again to be watching for pressure closely.

I’m using R23 in a 6mm creed.

105 Bergers will go quite fast with a stout load.

Brass is in decent shape after 4 firings, however it is a hot load. Annealing will probably need to be done after the 5th firing.

Accuracy had been very good.

Temp sensitivity seems non existent.

at 39.8 grain of 4350 and 2953 fps shooting .155 groups at 200 yards why change this barrel will last a long time

 

[john pruitt]

I know that RL26 works great in the 6.5 Creedmoor.

Have people been trying it in the 6 Creedmoor yet?

If so what are the findings?

Brian

I use re16 it works great in my 6 creed I believe re26 would be to slow

I have also been using RL23 in my 6 Creedmoor. it shot well with Fed 205 primers, but just for a test I decided to try a hotter primer with this slower powder. I tried Remington 7.5 primers and the groups at 600 cut near in half... Great combo. I use this with Berger 108 LRBT.

I am about to receive 2x 6Creed barrels; one for a hunting rifle and the other to replace my 6SLR match barrel. I shot 1000rds of RL26 under 115 DTACs in the SLR. It worked like a champ producing sub 1" groups at 300yds for the first 1000rds. My load was 44gr of RL26 in Winchester brass using CCI 200s. This produced 3040fps. I slowed it down to 3000 to meet speed limits of the match I was shooting.

I was worried about temp stability but to my surprise found it to be very stable. I even temp tested my loads. Put 5 in my gunbox in the garage(Ambient temp 55*), 5 in the fridge set at 35*, and 5 under a glass measure bowl upside down on a black foldgers lid in the sun. 85*. Verified the temps using my Kestrel and a Milualkie heat gun. A local indoor range is 10mins away, so I taped the cold rounds to a soda can and wrapped it in bubble tape and put it in a small lunch cooler that had been pre-cooling in the fridge. I left the 55* TDs in the gunbox, and wrapped the hot rds in see thru, large cell, bubble wrap and stuffed them in my dashboard to ride in the hot Colorado sun. I also laid my kestrel next to it to keep an eye on them as I was worried about maintaining a consistent warm temp. Got to the range and shot the rounds, hot, cold, then normal. To my surprise the ave MV varied by about 5fps. I was dissapointed with the results bc I knew if you didn't see it, chances are, you won't believe it. At any rate, I developed this load in early February and shot it thru this summer in Colorado and New Mexico. It proved to be very stable.

I have run out of RL26 and since switched to an old half keg of 4831SC. I am shooting 45grs of SC under the DTACs at 2990fps. Barrel has 1200rds on it now and is going into the Rocky Mountain PRS finale.

6SLR, Winchester brass, DTACs, and RL26 have treated me very well. I am on a quest to compare barrel life and load stability over a barrels life in the 6 Dasher vs. a larger but sandbagged 6, like the SLR at 3000fps. While the SLR has been great to me it still has way more case capacity than I need to run 3Kfps. Which admittedly serves to keep chamber pressure down My hunch is that 6 Creed will be the sweet spot to launch a Dtac at 3K with mild chamber pressure. Thus my change and interest in RL26 in the Creed.

I will be getting the hunting rifle tomorrow and won't be shooting the match barrel until the SLR is toast. I have a ladder of 4831sc loaded first but will try RL26 next. This is a new lot of powder. Peterson SRP brass. Both barrels are Proofs and will be getting the same reamer(.120). Pretty much everything will be the same between the two besides 4" of length.

Will let you all know...

 

[reubenski]

Haven't reached pressure with RL26 yet.

Bighorn Origin
Proof Carbon 22" 1:8" .120 FB
Peterson SRP, CCI450
105 class bullets
H4350 40.3 = 2960fps (Pressure at 41.5gr)
RL26 43.5gr = 2920 (Pressure at ? gr)
H4831SC 43.5gr = 2860 (Pressure at 43.5gr)

 

[reubenski]

I weighed all three brands of brass. AVE over 5 rds for each was:

Alpha
157.60gr ES .68gr

Lapua
169.60gr ES .44gr

Peterson
170.45gr ES 1.74gr

Haven't shot any Lapua or Alpha yet.

 

[waterdog]

Lots off good information on this thread!
Thanks guys.

 

[waterdog]

Anyone have any new info for us? Has anyone used the 6creed for deer or coyote hunting? Great thread!

 

[MTlager]

Shot 4 deer and 2 antelope with 115's in a 8 twist 29"barrel 6 creed running them close to 3150 with RL 26 this year. 3 of them between 700 and 800 yards the bullet still made nice exit hole thru the shoulder ! Dead on impact. Massive blood loss. Very accurate hammer. Elk next.

[daniel brothers]

WOW... tells us more about your setup Lonnie

 

[Beeman]

Lonnie is that with a 115 Berger Hunting? What kind of speed could a guy get out of a 22” 6 Creed with a 115 Berger? I’m having a dilemma on what 6mm to chamber. Want to run a 115 at 3050 fps minimum with a 22” barrel.

 

[MTlager]

Yes on the hunting Berger's. I had a low round count dasher barrel that I had the threads cut off and rechambered to 6 creed on a Curtis Axiom single shot action that ended up at 25 1/2 inches long. Using it for a hunting rig now and running it just over 3100 fps with RL 26. 8 twist barrel. Depends on what twist you have ? Might lose some velocity with a 7.5 I'm also 4600 ft plus in elevation. That 22" should hit 3000 no problem, maybe 3050 depending on barrel and action. Could go to a 243 win for a little more case capacity.

 

[Beeman]

Thanks. Barrel is going to be a 7 twist Benchmark. My original plan was to chamber in 6SST (Sherman Short Tactical). But I am having a hard time finding a SA mag bolt face up here in Canada. Without having to pay $1500 plus for a action that is. I'm at 1400 ft elevation and wanted a 7 twist to ensure I could shoot any upcoming new high BC bullets or all copper. This is strictly a hunting gun. How do you like the CURTIS AXIOM? Do you have any other custom actions to compare it to? That action may be a possibility for me as well as a Bighorn Origin. Never seen or handled either the Curtis or the Bighorn. Sorry for the derail.
