I saw this load in a newer manual recently, so I decided to try it... It was using H 4350... a powder I usually don't purchase as I have had better consistency with IMR's version instead...

I went out and did these tests, and now I can't remember which reload source I saw it in, and can't seem to locate it....

So take this with as many grains of salt as you want... If you play with it, work up from lower, and this is only posting MY results... to share only... not to get others to try it...

However, I thought a few would find this interesting...

bullet: 180 grain Rem Corelokt
Powder: H 4350
Primer: CCI/LR
Brass: Remington Used several times before..

Rifle: 1917 Enfield, 26 inch factory barrel...

Bullet seated to cannelure....

58 grains: 2864 fps
59 grains: 2896 fps

59.5 grains: 2900 fps

60 grains: 2956 fps...

the 2004 Hornady Annual Manual lists the pressure at 49,300 CUPs for a 57.5 grain load of H 4350 and a 180 grain SierraSPBT...

anyone with a Quickload program able to calculate pressures on these???

Came home and reloaded each of the cases and the next primers all went in nice and tight...

and there were no problems when I full lengthed resized the brass....

This is submitted as a point of reference and interest only....

However, I thought a batch of you guys might like to check it out....

Seafire, you're likely operating well beyond 65,000 PSI, but so what, if your brass is taking the stress. What is so magic about 65,000 PSI as an upper limit, given modern bolt action rifles. The brass is the limiting factor. Besides brass is fairly cheap, and if the primer pockets get loose after 3 loadings, throw it away and grab a new case. Your thoughts? Regards, AIU

I've been able to pass 2800 with IMR-4350 and H-414 using 180 grain bullets and 22" barrel. I was thinking I was maxed or close to it.

I agree with AIU in that this is not a load to be taken lightly and might be too hot with a different lot of brass.

This much I know.....the old 30-06 can be pushed over factory specs easily in a good gun using good brass. You're at the threshold of 300 magnum velocities here.....as you say...the primer pockets are not expanding.....

The Hogden web site maxes out at 57.5 witch pushes a 180 grain bullet at 2790 , and generates 49300 cup. 24 inch barrel.
I looked at the .270 loads and they push the 270 up to around 5200 cup.
So If I were taking my 06 elk hunting ,
I would probably bump it up a little but I think 59 grains is about as far as I would take it,
Your barrel at 26 inches is longer than most guys have in an 06, but I would expect guys with a 24 inch to get up around 2950 and a 22 should be up around 2900.
I think comparing it to the 300 win is silly, you can hot rod the 300 too.
I love the 06, but personaly I tend to think of it with a 165 grain bullet.
A .308 caliber 165 grain bullet at around 2900 will flatten anything up to caribu if you shoot it strait , and if you go to a partition or tripple shock Barnes it is plenty of cartridge for Elk out to 300 yards, If I need much more I will shoot a bigger round.

Now this is a good thread about a fine cartridge. I don't push too far past 2750 with a 180 for my hunting rounds. H-4831 has given me the best accuracy and the most consistant velocity in two 24" barreled 30-06's.Brass life is excellent minimal stretch and no problems with primer pockets. Untill I came to this site I was leary about compressed loads. I have found as a few of you good fellows have stated in the past that full cases give better SD and ES numbers when run through the chrony.

I just bought 2 boxes of the federal HE 180 grain partition loads just to shoot through the chrony to see if they are close to the listed 2880 fps. Any Federal premium ammo I have shot throught the chrony has been very close to advertised velocity's. Gives me something to work towards in the long lapse between hunting seasons. Hopefully Fridy will be a range day and I will post the results as soon as time allows.

AIU;

I just decided to load up some of the brass in the specs that I had seen giving that data.. and see what I got...

I own a 300 Mag, so If I needed that velocity I would tend to use that....

But for those that don't, I thought the info would be of interest to a few others.. that is why we come on here...

I could see carrying this load in the field if I was elk hunting and wanted the extra punch and velocity.... I normally only load up about 10 rounds of ammo when I take it to the field to go hunting anyway....

I have also gotten into the habit of now disassbemling the unused rounds after hunting season... to eliminate the 500 to 600 rounds I had around here of 9 of this load, 12 of that load.. etc...

I stock pile varmint loads, but hunting loads, if I don't shoot them, I dis assemble them and back into the components boxes they go... exception.. I put the powder into small sealable yogurt cups, marked and use that for load testing instead of tossing it back into the large powder container.....

10 or 15 years ago, I would have been all hot to trot with a load in the 06 of 2950 fps with a 180 grain load... would have gotten excited and came home and loaded up a couple of hundred rounds of it....but now I am older, wiser, fatter and gray headed ( not sure if all of that is an improvement!)

But I do love to know the parameters of each caliber I use... knowing 06 parameters with a 180 grainer at 2950 on one end and a 110 grain SP at 1000 fps on the other, lets me know exactly what I can do with that rifle caliber if I need it for any particular job...I find a lot of utility in that information...

I had this load figured out before.

60 grains of H4350 and 180 grain corelokt was around 65,000 psi with winchester brass.

With remington brass it would be around 70,000 psi since the case capacity is several grains less.

Remington brass is strong and you probably won't get any physical signs even at 70,000 psi.
