Copper Creek has some of the new 156's loaded up. 2930 fps. 40" flatter at 1,000 yards then their 143 load. I may try a couple boxes before I load them. I'm running an extreme hunter. G7 .347

I really like the 156... my goal was 3050 FPS. I have shot almost 200 of the 156s now with HBN coating; also HBN coated my barrel before I shot them. I found a good node at 3080, but pushed them all the way to 3170 with Retumbo. If I could have stayed at 3140 I would have... but it was just too close to pressure and a good amount of compressed powder.
FYI... They shoot well at .005 off and .035 off the lands.... I ended up at .005.
I shot H1000 and Retumbo, Retumbo was better on both 150 SMK and 156 Berger’s... both HBN coated.

I have been getting good accuracy with RL-26. My load is running 2980fps. I’m using hornady brass and anything over 3000fps is burning up my primer pockets. No other pressure signs. I’d love to push them harder, but I can’t stand throwing once fired brass in the trash.
I also have a GAP xtreme hunter with an 8.7 twist. Has anyone tried the 156 yet with this barrel??
thanks

Thanks for sharing. I shot the some 156 EOL with Retumbo in RP brass, neck down, .014" turned. Using Gap reamer with .120" Freebore. Fed 215 mag primer, .020" OTL. Found a node around 61grs. I ran all the way up to 61.5gr and got only a slight click on bolt and figured it was max. Speed avg around 2950 fps with 25" barrel. Groups were 3/4" at 100 yards. Needs some fining turning but looks promising.
Trail rider, but yeah, yours was a pretty warm load too. I normally run H1K myself, so not as familiar with the happy place on retumbo
Huckleberry,
I forgot to mention my 156 EOL are HBN coated and I ran another test from 60.6 to 61.4 grs. Zero pressure issues using RP brass, Retumbo and speed was 2975 avg.
Found a good node from 60.8 to 61.2 held .4” triangle groups at 100 yards. Getting better and happy so far with results wither 156’s and Retumbo.
My old load was 61.5grs with bare 140 hybrids at 3060 FPS. Got 17 firings from RP brass and they were done.

Well my 156 EOL and Retumbo load is doing really well. Since its my hunting rifle, and very pleased with the results at 993 yards. Shot prone on natural uneven ground. Temps were from 53 deg with 5 mph wind with slight mirage from it warming up.

Just joining this thread. Some great information here. Thanks to all who have posted list data.
I'm hoping for 3100~ or more fps with the following;
Desert tech 6.5 saum barrel, 26in 1/8 twist, .298nk .120 fb
Ultra 338 suppressor
RL 26
Bertram brass is what I currently have (if needed will go Hornady or adg)
215 magnum primers
berger 156
From what I've read here this isn't terribly unreasonable.

I’m running 25” barrel, 156’s at 3000 with retumbo. No Hornady brass will handle what you plan to do. ADG might but won’t last long or maybe it will.
Not saying you can’t but have a hard time thinking components will live long at that speed. You might get a couple firings from the brass is what I’m thinking. My 2 cents
with the berger 156 it might be pushing it but the RL 26 is fast. and I'll be at 3000 elevation or more with could help.
hopefully someone has achieved it and can pitch in some advice.
if needed, I will just run between 3000 and 3100 wherever I find the node
currently running the 147 eldm at 3070 without a hitch at all. but that is retumbo powder.

I'm running a 26 proof 7.5 twist, 150 SMK, Norma brass BR2 and 60 gr of Retumbo with a speed of 3106 average... So its very doable and I have some brass with 10 plus firings.
Where did you get your barrel? Those specs look like the same ones I’m looking at for my SRS.

so the HBN is helping a lot with speed? and it appears you're coating the barrel as well as the bullets?
Hey I've had wonderful success with 135 Atips and 130 bergers with 62 grains of h1000 and 153 Atips using 59.6 grains of h1000. Does anyone have similar loads for RL26? Just looking for a starting point.
I have found RL-26 about 2 grains faster than H1000.......58 gr RL 26 = 60 gr H1000, but please start lower
I coated the 156s right out of the gate along with the barrel. So on that particular combination and caliber I didn't have a good comparison. I did shoot them in a Proof barrel without HBN and they ran into pressure at about 2990 FPS... same length of barrel. I don't feel that is a good basis to make a statement that they increased my speed per say though... my Proof has been slower than my Benchmark on multiple bullet combinations. I ended up slowing the 156s down again for life of the components.
I did do a comparison on a 22 creed with 95 SMKs. I ran them with H1000 and RL26 not coated then went ahead and coated the barrel and bullets. I was not able to get them any quicker than what I was shooting them previously without coating. I didn't necessary run into presssure, but they wouldn't make it to the target. They were coming apart just under 3100. It was 6.5 twist and I wouldn't cut a 6.5 twist for 95s again, I would run a 7.3 or 7.5 twist instead.
I am sorry I don't have a simple "yes or no", but at this time I stopped on the 22 creed as it didn't yield any added performance and I am building a new 6.5, just waiting on the barrel, and I won't HBN it.
Hope that helps!

Super helpful for comparing different powders. Thanks for sharing this!
Just picked up a 6.5 SAUM from P/X section and found this thread very helpful.
Reviving for any new people or more reloaders to add data.
Please refer to post #235 by @30cal user to data data.
Thanks @30cal user for starting it!!

Chopped the barrel on my XH to 20” over a year ago. Now getting 2,990 suppressed with Ultra 7.

Anyone happen to have done a work up with N540? Or a good place to start?
Using 215M, ADG brass, Lapua 139gr
26" Brux SS barrel, 7.5 twist, Sendero contour
Geared toward being suppressed
Thanks

I'd prob start around 48-50gr. Case fill will be low as that's a very fast burn powder to run in a 65 short mag. 560, 565 are much more common. Believe 540 is closer to Varget burn rate.
Thanks @4O6shootist
There is limited reload data for the 6.5 SAUM, I found a few on here and other forums. So was just wondering as I finally got some N540, along with N165 which will be my starting powder for the load development.

N165 would be a much better choice. Rl23, rl26, H1000, Retumbo, 7977, 8133, would all be better than 540. 540 is pretty much a 6br powder no?
