I'm away from home for work and I had a hunting buddy email me for a good start load for his '06 using H4831 and a 165. Normally I'd just glance through my manuals, but away from home this isn't an option. I know it's a bit slow for this application, but it's what he has. I didn't find much on the internet either so I'll ask you guys. Of those of you that use this combo, what are you runnin for charges? I figure he'll be safe to start around 57-58grs under the 165.
Thanks for the help,
Brett

Loaddata.com shows max charges of H-4831 in the 60 to 62 grain range for various bullet manufacturers.
Some samples: Hornady 165 SPBT shows 60.0 max at 2831 fps. Sierra 165 HPBT shows 61 grains at 2705 in a 22" barrel. Speer 165 any type shows 62 grains max at 2772 fps.
Based on that your 57-58 grain estimate to start looks spot on.
One can usually get up close to 2900 fps with 165's in the '06 with IMR or Hodgdon 4350, based on the velocities above I'm thinking he'll run out of powder space long before hitting max pressures with H-4831.
Hope this helps.

Hope this helps. I was going to say that I would think the 4350s would be more of an optimum choice, the 4831 would work better with the heavier bullets. It'll work, but the 4350s would be a tad better, velocity wise.

I don't think you can cram enough H4831 into a standard '06 case to cause problems for a 165. I have used 60 grains (or better) in mine with 180s for over 25 years without any issues. (And I now understand why the "foolish" comment of the more experienced reloader many years ago wasn't all that foolish. He said for the '06 it was simple enough to dip a case in 4831 -meaning the old WWII version which is now preceded by the "H", level it off, and seat a bullet. And that pretty much sums it up.) So, while 4831 is a bit on the slow side for the 165s, it will also hunt for you if need be.

Based on your comment that 4831 is what he has, start at 58 gr and probably work up to 60. I have run a lot of 168-172 gr match bullets with 60 grs, using that load for 600 yd competition.
However, he will probably have to use drop tube to get 60 grs in the case.
Find an old aluminum arrow, cut it to about 18" long.Tape a funnel to one end, if the right size,the arrow shaft will just barely fit into the .06 case. Drop the measured powder into the funnel slowly.
I attach mine to the side of my powder measure with rubber bands
As I remember,you cannot get enough H4831 in an .06 case to cause pressure problems or over loads,if 165 gr or less bullets are used

Too slow. Try RL19 which is the cat's azz w/ 165s in the '06.
Ok so now I've read the original post and realized that my advice above isn't what was asked originally.
Manual lists 61.5 as max w/ 175 gr SMK, so I'd start just under there and work up. Like others have said, drop tube'll likely be necessary.
Good luck!

I did not want to mention about dipping an .06 case,but that was the std way to load the 4831.Dip the case to full, tap on bench,re dip and seat the bullet. get up past 175 gr. bullets and you can get into trouble though.
4831 was .42 /lb. you could buy Mil surplus AP's, 150 gr, for .02 per round. Back then primers were .50/100. I sent many a thousand down range for 200 and 300yd work but usually used Sierra Match Kings for 600 yds.
It has been proven with slower burning powders in .06 size capacity cases, variations of 1-2 grains does not make a hugh difference in velocity/pressure or accuracy.
Guys, go back and read the original post.It stated he wanted to use 4831 as that is what he had.He did not request some other powder reccomendation.
I have use 4831 for many different cartridges. It might not be the optimum powder in all cases,but it will work, and quite effectively

And it's quite surprising how well it shoots and how effectively it kills, at least it did before chronographs were so simple and affordable. It's one powder I rarely buy in one pounders anymore (that is, when I can find 4831). It is a very versatile powder, if not always the very best choice. But then, I guess we're presently living in a time when we are forced by circumstances (of shortage) to make do with what we have. And I reckon many of us will learn some new things as a result.

I just checked an older Hodgon Manual
Starting for 165 gr bullet is 56 gr, 2381fps, 34800 CUPS Max is 61 gr , 2770fps, 44700 CUPS.

Bringing this one up from the depths to see how this turned out?
I loaded up 61grs of H4831+165NBT and got great accuracy @ 2700fps. 62grs shot just as good but I have not had a chance to chrono it yet.

BC74, H 4831 is too slow for the .30/06 in my experience. I have never achieved highest velocities with any bullet weight in this case using that powder.
I would move to slightly faster powders like 760/H414, the 4350's, or Rel 17.
A 165 grain bullet should be moving around 200 fps faster than the load you achieved.

Thanks for the info.
From looking around even 4350 shows big variation in velocity with loads. 57grs imr4350 seems to be standard and I have seen velocity online from 2650-2850fps with that charge. I tried imr4350 from my other two '06's and accuracy was terrible.
I have 414, I may give that a run.

Holy crap, 61grs of 760? Those are some great speeds with the 165's.

Oh yeah, working up is always a good idea, but daaaaaayyyym. Sloppy chamber, did you have it reamed after the smith played a game of dizzy bat?

I tried 30-06 loads w/ a 165 over H4831, but they were all compressed loads, and needed a heavy crimp to keep the bullets from backing out. Went to H4350 and get better velocity, accuracy, and not compressed.
