The lot of R26 I used acted more like R22.

AIU
thats intresting...i wonder what R23 would act like

One guy on 24 hr campfire was getting 2730 in a 20 inch tube with 200 accubonds and 2750 in a 22 in tube
that was with a charge of 61/62 gns of R 26
IF THIS IS TRUE/ACCURATE 2770 may be possible with a 24 inch tube

the best i have got was with MRP ~2730...
with R17 i get 2725...no compression issues

do you by any chance have a 06 with a 24 inch tube and standard chamber

I shoot a 30-06 Ackley Improved, 26" barrel.

I like Re25 with 180 grain bullets ~ 3000 fps.

I haven't tried Re23 or Re26 with the -06, only with my 300 WM.

Have you tried Re25 with 200 gr bullets in the std -06?

Regards, AIU

no i havent tried R25...I just think it may be to slow...but i think R26 just might be the go...but as one poster on 24 HR said he got 2750 with 62/63 gns in his 22 inch 06....pain to load as every case you load is compressed...lots of tapping drop tubes etc etc
be intresting what you get with R26 IN YOUR IMPROVED 06

I get 2925 fps in my standard 06 with 57 gns of R17 behind the 180 nosler

I thought RL22 = MRP, given lot to lot variation. As per the above, am not the only one.

Daniel,

I tried Re25 with 180 NBTs in the standard 06 with a 24" barrel and got 2825 fps, but with NO pressure signs at all. The case was packed full and the powder highly compressed.

My impression was that with a 200 gr bullet, Re25 might be perfect in the standard 06.

Worth a try!

R-26 is not the same as R-22 or MRP.
R-26 Made in Switzerland for Alliant Powder.
R-22 Made in Sweden for Alliant.
MRP is made in Sweden at the same plant as R-22.

The data I've seen on RL-26 would make it somewhat slower (although apparently a bit higher energy) than RL-22.

AIU
if i can get hold of some R25 i will give it a try, but i will definatly try R26...its in a class of its own i dont use the 180 gn proj any more...i use the 200 gn nosler part for everything with great results......and if i can get R26 to perform in the 06 like others have...it will just make the 06 just that little bit better......i think another few years with improved powders and 2800 fps might be doable with the standard 06 and the 200 partition

STONY CREEK
i think you are spot on,R26 is a higher energy powder .... bigger brother to R17

Daniel,

If you want to MAGNUMIZE your 30-06, you might consider rebarreling to a 338 //30-06 Wildcat, such as

1. 338 Gibbs
2. 338-06 AI
3. 338-06

im happy with my 06 with 200 gn noslers @2700, i have shot a truck load of Big Game animals if i can get any more then 2700, thats just a little bonus which im happy tp take!!!!
im having a bit of a play with the 200 gn barnes LRX with R17
i do have a 375 and 416 Ruger on a satterlee action, and i just love that 416 , i have gone into casting big time for the 416 and i just love it, a 400 gn cast bullets @1500 fps shooting a touch over an inch at 100 yards, and with 65 gns of varget im getting 2150 and printing a triangle at 100 yards.....so im happy, infact very happy

Daniel,

The 30-06 is a extraordinary cartridge - maybe the best all around cartridge ever created.

I'm not surprised by you satisfaction with it.

Putting that 200 gr premium bullet into the boiler room will - I'm sure - take care of all your needs.

Squeezing another 50 fps will likely not change a result.

Regards, AIU

You may want to try the new RL16 in the 30-06 as well. I haven't tried any 200 gr bullets with it but I am getting 2815 FPS with 180 gr Accubonds out of my 30-06 with a 22" barrel.

im getting 2925 with R17 thats with 57 gns
that load sings!!

AIU
you are right, 50 fps will not make any diffrence, but with new powders its a slow incremental journey.....15 or 20 years ago 2800 with the 180 was a max load, today its 2900, as powders have developed and improved
And i just take the little incremental gains as they present them selves, and go hunting!!

Daniel,

While developing loads in my 06 AI, I found that 66 grs of MRP gave me 3200 fps with 165 NBTs and Acccubonds out of a 26" barrel.

Wow, I thought, and they worked well as long as they were freshly loaded.

This was a heavily compressed load, and over time - say more that 6 months old - I noted the start of erratic pressures, erratic velocities, and less accuracy.

I pulled the bullets, and I found that the powder had become encrusted into a rigid mass, and I had to chip it out with a depriming tool.

Bottomline: Be careful with super heavily compressed loads, because over time the powder grains can become stuck to one another, which appears to change the burn-rate characteristics. MRP seemed particularly susceptible to this problem, but not unique to MRP.

Now, I always use freshly loaded compressed loads. Non compressed store better.

Also, with highly compressed loads, it's hard to control OAL, which can affect velocity variation.

Minimizing velocity variation is very important with long-range shooting.

Wow that's impressive! I could keep dumping in more of the RL 16 since I'm not showing any pressure signs yet and probably get close to that, but my accuracy really came in with this load. I'm shooting it in a Remington 700 Titanium that is a little less than 6.5 pounds scoped and loaded which is an absolute joy to carry in the mountains and it's averaging about 5/8" groups with this load.

i have had this load pressure tested, so i know where i stand, reloader 16 is an unknown quantity to me
