Home Forums Hunting & Shooting Ask The Gunwriters 30-06 +p with low temp sensitivity

Speer's #14 manual lists 58.0 grains of H-4350 with a 180 grain bullet at 2756 fps. Working up to that same load with a 180 A/bond gives me 2725-2740 out of a 22" barrel. Being right in line with factory velocities I figure that's as good a place as any to stop.

Bugger,

I'm getting about the same velocities as bwinters in a Sako , 24" barrel and use H4350 and with Noslers ballistic tips except I use 61 grs for the 150's and they run around 3100 fps.

Some of those velocities can be beat with a good chambered custom barrel depending on the length. Read what mule deer posted again. Superformance is an interesting powder to try along with Ramshot hunter.

There was a thread on taking the 30-06 to 65000 psi on another forum some years back and was an interesting read. I believe the pressure testing was done by a guy that worked for a large powder company..

If velocity is your only goal, I'd just get a magnum caliber with a long barrel. I'm a classic caliber man and see no need for super hot magnums. Jacking the pressures uo in the 30/06 is not a good idea.
Faster bullets can actually reduce penetration due to rapid premature expansion, as well as causing significant meat damage. I recall a discussion in Atlanta about this, among a group of magnum afficionados at a gun shop. Eventually a bet was laid. $100 if I recall correctly, that slower calibers would penetrate further than "magnums". The 2 calibers were 7x57 Vs 7mm Rem Mag and 308 Win Vs the 300 Win Mag. Loaded to factory specs, using the same bullets. 139 & 180 gr. respectively. The medium was wet Atlanta phone books, stacked in a cardboard box. I won the bet, as the standard calibers penetrated 25-30% deeper than the magnums.

But some people get their panties in a wad when anyone suggests sticking to the design pressures & velocities of a very capable cartridge..

No reason for personal insults in a rational discussion.

brayhaven-

I'll be nice and polite.

I believe you and your tests report.
I respectfully suggest that you try to duplicate those same tests using 'premium' bullets. I think you'll find 'different' results.

The comments made by others that have made up facts and ridicule a request deserved the comments I gave.

There's +p loads for the 257 Roberts. 7.9x57 mm and 7x57's are loaded above 'standard' pressure. In revolvers there's loads for the Ruger only.

Ken Waters had three sets of pressures for the 45-70. Springfield, old lever actions and bolt action or falling block.

38 Special has a standard load and a +p load.

By running a chambering reamer into a 280 and making it a 280AI, the pressure can be in creased as in almost any "improved" cartridge.

But suggest increasing pressure in the 06 will cause people with minimal IQ to ridicule the suggestion.

My most accurate load in my old piece meal 06 will shoot <.25" groups. The load is 50.1 grains of H4895 and 180 grain flat based Hornady Interlock bullet.

The case life is good, extraction is good, etc.

According to what I've found this is a 'excess -heavy' load in today's manuals.

With my old Springfield 03 I shot a .15" 5 shot group with an overloaded by today's manuals. Again it was H4895 but with 150 grain bullet. I used this load in rifle silhouette.

These loads came out of the original Hornady reloading manual printed in 1968.

Back then they didn't seem to have accurate pressure sensing equipment just as I do not.

So what pressures should I be getting with these loads.

Finally, why is it that I should put up with moronic comments for asking a question?

Bugger

'moronic' comments usually come from .....

As it turns out we have NEW powders that produce the increased velocities desired AND the loads are published in 'newer' loading manuals.

Some folks are lost in the 70s or earlier.

Jerry

Bug hole groups only at extreme velocity/pressure? I don't doubt you, but it does beg the question--why? What earthly reason is there to stress an ancient '03 Springfield with loads like that, no matter how accurate such loads may be? I submit there are better platforms for such folderol, and other cartridges better suited to that kind of sturm und drang
than the .30-06.

Again - this.

There you go with them technical terms again!

I'm using R17 in the 30-06 these days. This pressure chart was one reason I tried it. Screenshot from another web forum, for those that haven't seen it...



I wrote to DK and he told me the test barrel was 24".

bob-

uh huh!

Remember some 'don't' want to see.


Jerry

That's amazing accuracy. Almost unbelievable! 🙄

Same guy ran a bunch of tests a few years back using 180s and 200s. That is where/why I run 180s in an 06 to 2800 with the same powders.

Re 17 surprises me. I was getting 2850;2875 with 55 grains and thought it too hot so never loaded them again. Re 17 is accurate in 06. I may revisit now I know the skinny on the pressure. Thanks for posting. Mind sharing the website?

Just the nature of the Internet Beast.

Might want to dust off your ignore function.

I don't mean to sound like I am in any way an expert on this, but if I were sitting at bench at the range, and a fellow came up to the next bench over and said he'd been playing with "30-06 +P" I would listen politely while he was setting up and by the time he was chambering the first round, I would be on the way to the car.

In fact, I've done that a couple of times-- not with 30-06, but with a fellow who claimed his 30-30 shot like a 30-06, and another time with a guy seeing how far he could push a 7mm Rem Mag mixing powders together. The point is, that you don't know what's going to happen. Neither does the other guy, not really. If I'm not going to go over SAAMI, why should I be sitting next to a guy who will?

Buy some Lapua brass and a copy of Quickload and work your way up.... You'll know when you've gone too far.

If you feel the need to hot rod a rifle may I suggest Ruger #1 45-70? BTDT

bobnob17,

Is there a chart with RL17 and 200 gr bullet data?

My happy spot with RL-17 and a 200 grain Nosler Partition is 55.0grains of powder.

Here is my load with RL-17 powder and 200 grain Partitions.
