Which powder will give me best results
R17
Stabil 6.5
Ramshot Hunter

Looking for 2700fps

Staball gave me the velocity but the accuracy suffered. I tried H4831sc, and got a little over 2700fps and great accuracy with book max.

H4831 will definitely do the job. I have not tried the others mentioned.

The Nosler on-line reloading tables show a couple of others making 2700 with the 190gr ABLR in 30-06.

Wow, yes there are some options

I forgot to add I have a 20” barrel

So it needs to have a book value of 2750fps or something

R26
And
Norma MRP
Seem to be unicorns

With a 20” barrel, you need to be looking at 2600 fps tops. Most manuals use 24-26” barrels for testing and those are gonna run 100-150 faster than you’ll get with the 20” barrel. Pushing for 2700 in a 20” barrel seems a bit over pressured.

Try Superperformance. I'm averaging 2660 and great accuracy with the 200 Terminal Ascent and a 22" barrel.

That sounds like a jewel of a load. Would pretty much do it all.

Súperformance should get me there and I have it on the shelf
I don’t have that powder in quickload
Nor can I find data online

Thoughts on where to start?

Rl17, Rl26, H4831, Rl22 should all get you there

I settled on Staball 6.5 under the 190gr ABLRs, ran around ~2,600 fps out of my 18.5".

H4831 & Reloder 22 won’t go fast enough per book value

I have tried reloder 17 and don’t get the accuracy
2touching 1 1.5” out

I am going to try superformance and go from there


Unless someone can tell me where to buy R26 for less than $1000/lb

When I was shooting 200 NAB in my 24in 30-06, I could get 2700 but only with Re26, and exceeding published max loads by 2 grains. Exceeding published loads depends on your comfort level. Most published 30-06 loads stop shy of 60,000 psi, most are in the 58,000 psi range. The cartridge case and modern rifles can handle 65000 psi. If you linearly extrapolate a line through published data, you'll find 1 gr powder is about 3000 psi and 30 ft/sec. Give or take a few psi/fps. But - you have no way of knowing the exact pressure unless you get it pressure tested. I'm comfortable with exceeding published data on the 30-06 by a grain or 2 - but the velocity increases must also be reasonable. I would not be comfortable with adding 2 grains and seeing velocity increase by 125 ft/sec.

All that said, I doubt you'll see 2700 with a 190 in a 20" barrel at sane pressures. A 300 WSM gets you there......

I thought the same, not much I wouldn't hunt the world with that combo.


I used Federal Load Data, my load is 56.5 grains.

Hodgdon also has data for the 180s to give you some reference.

Saw 2lbs of R26 at local Sportsman’s today for $53 a pound. Might want to check them out

That’s a pretty good price.

Just passing it along. Figured if it was on that shelf maybe it's available on line. (?)

In regard to 30-06 with 190 gr bullets;
Published data max loads:
Sierra #3........26 in barrel...........190 mkhp...........58.5 gr H4831....................2700 fps
Sierra #5........26 in barrel...........190 mkhp...........58.3 gr H4831 sc................2700 fps
Sierra #6........24 in barrel...........190 mkhp & tmk..57.6 gr H4831 sc................2600 fps
Lee modern HL... N/A...................190 jacketed.......59 gr H4831......................2710 fps
Hodgdon #26......N/A...................190 jacketed.......60 gr H4831......................2737 fps
Hodgdon 2023..24 in barrel...........190 Horn btsp.....61 gr H4831......................2668 fps
Nosler #8........24 in barrel............190 ablr/c comp..57 gr H4831..................... 2613 fps

My comments:
Any time pressure is listed for the 30-06 with H 4831, it is 10,000 to 15,000 lower than peak pressure listed for the 270. Whether that listing is in CUP or in PSI. The 30-06 is always maxed out at much lower pressure.......WHY? It is the same brass in the same rifle action.

Is it simply because the loader can not be bothered to compress his powder enough to get a larger load into the case?

It has been long recognized by savvy reloaders that one can not squeeze enough H4831 into a 30-06 case, and still seat a bullet to SAAMI COAL, to get into trouble.

Using appropriate techniques to compress my powder charges, this is the data I developed.

My Data: 11-21-95

Winchester 670; 22 inch barrel; H4831; 190 gr Hornady btsp, CCI 250, Remington brass.
62 gr ......2681 fps
63 gr.......2719 fps
64 gr.......2775 fps...Yes, you can hear the powder crunch as you seat the bullet. No crimp, but I never had one push the bullet even a little bit out of the case.

I was also able to match these velocities with slightly lower charges of IMR 4831. But at anything over 2800 fps IMR 4831 began to slightly crater the primer around the firing pin.

You would expect to reduce these velocities by 50 fps in a 20 inch barrel.
