3006 ,150 gr, 3225 fps

Hodgdons max load using a nosler 150gr was 60.0gr of win760 and it netted almost 3000fps. Another 3gr of powder in a barrel 2" longer I'd probably say your chrono is working just fine.

I'd say for sure, esp with say a Fed mag primer. My Winchester 1917 (26" barrel) registered 2960 fps avg with a 147 gr FMJ/BT, an 56 grains WW760. My Rem 700 with its 22" barrel got 2680 fps with a 150 grain Sierra Gamekings, WW std LRP and 57 grains of WW760. Same rifle got almost 2900 fps with 60 grains of H414, CCI 200 primer and the same bullet. These were shot and recorded in 1995, with propellant from the time. Good luck.

I experimented with WW760 many years ago in (2) 30-06 's. It was all I could do to get 60gr in the old WW Super 3006 brass back then which was some of the toughest brass and also most case capacity available at the time. You got 63.2gr in there.... wow. You probably won't be able to do that with most 30-06 brass due to internal capacity.

Any velocity that I've recorded with a 30-06 and 150gr bullets just hints at 3100fps at best out of std length barrels. As a matter of fact I give up using WW760 due to the compressed loading and lack of velocity at that time.

But anything is possible.... and you got a little more barrel. I have an AR with a 16" barrel and a decent load of Benchmark with 50gr bullets and the velocity that I get.... I've been called a BS 'er when I tell them. I let them run the chrono at the range to change their minds. So anything is possible. Tread lightly though... you are up near the boundaries of what a 30-06 is really capable of delivering safely. So, possible... yea. Just be careful.

The old 30-06 can still deliver the goods even without the word magnum tacked on the end of its name after 100+ yrs!

It shows ww748 56.1 max . At 55 gr. 3100 fps. The primers had significantly over pressure sign .

WW748 has been kinda squirrely for me. 52 grains in my Rem 700 w/ a 150 grain SGK got me 2810 fps. Going up 1 grain went to 2920, but pretty flat primers. This was from 1994, with propellant from that time. Have seen this before with WW748, but shot back in 1984 (no chronograph for me back then)... Seems kinda peaky, and I think/seem to recall cold weather made it exponentially worse, as did moderately warmer temps?

Holy Moses! That’s fast. If it’s for hunting, make sure you either have a really well built bullet or you aren’t shooting anything very close.

The Frontier brass is full, flat base hornady 150gr. Primer Fed 210 , WW760 got it some time in the 80s

Shot a ton of those Hornady 150 grain Spire Points. Seem to recall w/o checking that the bearing area on these, is less than the Sierra GK? Always shot well, but seem pretty fragile at higher velocities... But the SGK's seem pretty fragile too.

I have had lots of weird readings from my Chrony Chronographs. The errant readings fall into two categories: 1)off axis bullet travel over the sensors. The chronograph has to be as close to perfect, in line with the bullet travel. And the bullet should go right over the centerline of the chronograph sensors.

And, 2) unburnt powder residue. Messes up a chronograph all the time. For some reason, long barrels have a bad affect on my chrono's. As an example, the Schmidt Rubin M1911, my chronograph registered some great velocities, if they were only true!

I think the velocities were so high because of the muzzle blast. The chronograph really shook after each shot. The next time I took it out, I made sure the chrono was a long distance from the muzzle, and the velocities are radically different, and, close to what I think they should be. There are time when you need to move the chronograph out, away from the muzzle blast. Blackpowder is one of those times.

So, move your chronograph out. And, shoot over it with something like a 22 lr. I have been blasting a case of Rem Target 22lr this way, use that ammunition as a calibration standard before I start banging away with the big stuff.

Keyfer 55,
What is your end result? You going for velocity with a 150gr bullet or you just want pure accuracy?

For pure accuracy.... I have my old standby load for the 30-06: all the H4831 you can get into the case with CCI 200 primers with a 180gr bullet and it works in several different 30-06 rifles I've loaded for myself and friends. I get 2690fps with 180gr Noslers out of a std 22" barrel with that load and it shoots well under an inch at 100yds. Sometimes... well under an inch!

For 150gr loads IMR4064 was always good to me and could get 3000fps plus with it if you want to stay with 150gr bullets.

Good luck. Let us know how you make out with that 26" barrel. Interesting...

Been saying the same here for a lot of years. First F1 I got in 1994 worked pretty well, but was very sensitive to having just the right light, and some err messages. Master F1 I got in 1997 was a total POS. Would have to use a NASA level sun angle instrument, and not be .000000001 mm off of both centers to get any reliability, and even then a ton of no shot registers, partial err, crazy velocity readings, whatever. It also read about 6-8% fast when it did work. Was NOT an issue with how it was set up, battery, or proper use of screens - It was simply garbage. Tried to do an upgrade with Shooting Chrony, and was told despite their never ending promotion of a half price credit on a new chronograph when you turn in an old model, they reneged, saying my "green" version was exempt.

That got them having me tell anyone who asks about Shooting Chrony brand, to look elsewhere. Got a ProChrono Digital about 10 years ago, and what a pleasure... Pop in the battery, add screens and shoot. Wow, what a concept it works. 99%+ reads, huge forgiving shooting area, and velocities are in check. I know some folks love/have good luck with SC, but just how they treated me even if the product worked perfectly, turned me off to them forever.

Funny you should say that because 60.0 grains of H4831 with 180 Sierra PH's is the most accurate load I have found for my M70. One of the few sub MOA ever for that rifle. I only get 2605 fps but it is so accurate I still hunt with it.

My 22 inch barrel 06 with 150 Speer and 760 gets ~3,000. Add 4 inches of barrel and it's possible.

Just installed a 26 in barrel on a savage mod 110 , max load 63.2 gr .win 760 , cronoed 3 rounds over 3200 fps. Is it possible? Should I try another crono? Has anyone else got that
that velocity from a 06 ?

Quickload gives 3227 ft/s for a Sierra 150gr SPBT at 3.25 OAL with 63.2 gr of Win 760. So I would say you got exactly the expected result. It also says it's a 65KPSI load (SAAMI max is 60KPSI). What you have discovered is that if you crank up the pressure, they go faster

This is probably a nominally safe load in a healthy modern gun (most modern rifles chamber the 65KPSI cartridges with no changes to action or barrel) but 760 is a notoriously temp sensitive powder. Your load is probably pushing proof territory at high temps. I would feel better capping it at about 61.7gr.

I want to get 2800 with 180 gr Berger.

760 with a 26"barrel would get just to 2800 but the max will be closer to 55.5 gr another powder for that task you may consider, rl22.

57gr of H4350 gives me 2800 fps from my 22" Winchester 70 with several different 178-180 gr bullets with good accuracy, that is about 1/2 gr below max. Not tried the Bergers, but don't see why it wouldn't be the same.

3200 fps + with 150's seems unsafe with any barrel length. If you're really that fast I think you are over loaded. Around 3100 fps is as fast as I've ever seen any load and a 26" barrel just doesn't add that much over a 24" barrel. Less than 30 fps with 30-06. I've hit 3050 with my rifle and max loads of H4350, but got better accuracy backing off 1/2 gr and still was a bit over 3000 fps.

Ill have to check my data but I want to say I've gotten 3200fps or very close with Superformance and 150s from a 24" barrel.
I KNOW I've gotten just shy of 3100 with 165s, that data is also completely unsafe in older cases like the lc69s I've got a couple hundred of Capacity is 4gr (there bouts) less than the Nosler brass I used.

If it sounds too good to be true it usually is. That load is over-pressure.

With all the data available today for free why would you use 36 year old data from 1982?
With a 150gr bullet and W760:
Hodgdon lists a a max charge of between 57.0gr and 60.0gr depending on the bullet.
Hornady 9th Edition goes to 59.1gr 3000 fps
Hornady 10th Edition goes to 60.0gr 2950 fps
Nosler #9 is 57.0gr w/2912 fps
Lyman 's 50th Edition says 56.0gr max
Speer #15 goes to 57.0gr 2814 fps
Even Speer #8 which is known to be hot lists a max of 60.0gr.

My point being, if all these sources say 63.2gr is at least 3.2gr over max it probably is especially since the velocity numbers are high.

Just a note, even though I quoted mostly manuals online data agrees and is available from Hodgdon, Nosler, and a host of other free sites.

I'm sure most powders have undergone changes seance that 3rd edition was printed. The case didn't look stressed the primer was a little flat. I'm not one to push the limit, I've got five manuals, this is was fastest load data out of the five manuals. Just wondering if anyone else got those kind of readings ?

Powder has not changed but testing methods have.

I don't think that I get 3200 fps with my 300WSM and it max's out at 70grs. by the Hornady book, but it is a 20 barrel. The same book puts your max load at 59.1. The Lyman 50 edition puts max at 56. Makes you wonder doesn't it?
