I have some 215 Bergers to give a go in the 06 and WSM as well. May find a good yote load...grin

Casey,
Laughin'!
But a few years ago I decided to test the old handloading pressure signs, including case-head expansion, and worked up loads for three rifles. One was a .270, and I worked up to 58.5 grains of Reloder 19 with a 130-grain bullet (can't remember exactly which bullet now), no problem. Took them to the Western Powders lab and they averaged 68,000+ psi. And what was the velocity on that load? Assuming a "new" unknown powder workup on a 270, what is your "target" chrono velocity that correlates to "max pressure"? MM

Not to hijack Dober, but here's a question; one of the most popular handloads in post-war reloading-dom is the 270W with 58gr of H4831 under a 150gr bullet. I've chrono'ed at least a thousand rounds over the past 30 years, ran 50-60 rounds through an Oheler Ballistics Lab and stayed under pressure for those rifles. Yet, today's (peizo tested?) load manuals are now limiting H4831 to the 56gr range. I'm sticking with 58gr of H4831 for my loads--am I gonna blow my head off? Casey

Casey Kinda why I asked JB what his parametr for a 270 are..........I am very interested to see where he may have been in the past vs now. Casey, I am where you are with it; my velocities for the 130's are typically around 3075-3100 & with the 150's around 2950, both with Partitions from a 22" barrel. Sorry to HJ Dober's thread. MM

I just got back from a quick trip to the hills to test out Seafires load for the 200 NP and H4831 SC. Started at 60 grains and moved up to his load of 63.5. End result, out of a cleaned 22" barrel I got 2,750 mv. I spect that once that bore dirties up a bit that it will be pushing 2,800 mv. No signs of pressure at all from the load. The rifle is a 700 Ti and I have a scope on the way for it. (I shot over the chrony w/o a scope.) Once I get the scope on next week. I'll take one piece of virgin brass and my loading stuff to the range and see how many times I can shoot it without the primer falling out. I'm going to try that load, likely with the 200 NAB though.

Hmmmm. I've got a .30-06, 200 gr Nosler Partitions, H4831sc all on hand.... Of course there's also a .300 WSM in the safe, so perhaps no reason to push my ol '06 so hard.

If there's one thing that legions of handloaders have shown it's that going over SAAMI max by a "little" ain't no thang.

Agree - the WSM has been shooting real well with 200 gr Noslers & 210 gr Bergers over H4350, right about 2815 fps or so.
Didn't think much of the .300 WSM when it was introduced, but made a screamin' deal on a Model 70 a few years ago and dang, it's turned out to be quite a rifle.

Brad, we've both killed with the 338 win mag. I used 250 NP's in it to kill elk.
As it looks or appears now, an 06 that shoots a 200 NP at 2,700 or 2,750 would in my mind would out penetrate and out fly a 338 win mag shooting a 250 NP. Something to be said or thought about there.
(I've also killed 6 elk using the 200 NP out of a 300 win mag. Complete penetration though shoulders with it at distances between 400 and 650 yards. One bullet killing two elk at 600+. So I know the bullet works.)
Put the 200/2,750 NP in a 6 lb package and my ballistic mind goes bonkers with elk hunting possibilities.

As PS said:
I was using the 220 Partitions as I did a test using damp magazines and the 220 Partitions outpenetrated everything else by quite a bit. Next in line were the 200 Swifts and 180 TSX ( which gave identical penetration), followed by the 240 Woodleighs PP and finally the 220 Woodleigh RN.
The 220 Partitions equalled 300 gr Partitions from a 375 H&H and beat 400 gr DGX Hornady softs from a 416.

I'm not either but Elk are not coastal Brown Bear and don't need the penetration and lack of speed/trajectory the lighter weights give for Elk hunting.
To each his own and the two sides to every story.

That's what I'm thinking too! Of course, shooting my 6 1/2 lb 06AI with 200gr Pt's at almost 2800fps already makes my mind go bonkers for a few seconds before my vision clears...... Casey

Hecks ya! How does that thing feed and what barrel length?

Since this is the "Ask The Gunwriters Forum" lets see what they have to say,in fun....What they have wrote about the 30-06 and bullets heavier than 180 grains....
John Barsness Today I don't think there's a real need for anything bigger than a 180-grain bullet in the .30-06
Craig Boddington I also don't have much use for bullets above 180 grains. Additional bullet weight--200 or 220 grains--offers a hedge against bullet blowup as well as increasing penetrating potential. There are times and places, such as using the .30-06 on brown bear or when Hemingway used his Griffin & Howe Springfield on lion, rhino and Cape buffalo. I don't use the .30-06 for such game, so for me a good 180-grain bullet is all I need.

Sure, but I'm looking at a rifle/bullet combo for chasing the heard through the thick and occasional clear cut. Want a bullet that goes up a bulls six straight and true.

Without trying to start a fight, just HOW do you get 2,700 out of 200gr bullet in an 06 anyway. Been shooting one for 40 years, and believe that 2,500 - 2,550 about tops, especially with the 22" barrels so many wear.

MD, I'm not one that necessarily thinks that the books are the absolute end all to maximum loads. As an example you and I use pretty much the same loads for 9,3x62 which are above the low pressure loads listed but still under modern rifle pressure limits. I think what you list here sounds pretty reasonable: Hodgdon's data shows two different 200-grain bullets. The max load for the 200 AccuBond is 59.0 H4831 at 2586 fps and 49,400 CUP. Max for the 200 Speer is 57.5 H4831 for 2577 fps at 49,400 CUP.
If we increase the pressure to 51,500 CUP (the max listed by Hodgdon for any .270 loads) the increase would be about 4.35%. Divide that in two and we get an increase in velocity of 2.17%, for around 2640 fps.
Since velocity increases at the same rate as the powder charge, this means an increase to 60.8 grains with the AccuBond and 58.75 grains with the Speer--and even then we're still probably going to be under the maximum SAAMI psi pressure for the .270. It's too bad the Hodgdon data isn't in psi, rather than CUP, since psi data tends to be a little more accurate. Problem is that your charges listed are just the starting point for some...... I just got back from a quick trip to the hills to test out Seafires load for the 200 NP and H4831 SC. Started at 60 grains and moved up to his load of 63.5. End result, out of a cleaned 22" barrel I got 2,750 mv. I spect that once that bore dirties up a bit that it will be pushing 2,800 mv. No signs of pressure at all from the load. The rifle is a 700 Ti and I have a scope on the way for it. (I shot over the chrony w/o a scope.) Once I get the scope on next week. I'll take one piece of virgin brass and my loading stuff to the range and see how many times I can shoot it without the primer falling out. And not to mince words, was it here or on AA where someone trying to duplicate Seafire's Blue-Dot loads blew up a rifle? Where do you set your upper limits? I'd imagine you could probably feed a Remington model 700 70-75,000psi loads almost indefinately without a Kaboom but I don't think it's really all that smart to try and find out. There's so many other rounds that can shoot 30 caliber 200gr bullets to 2800fps including lightweight rifles I just can't see the sense of trying to do it with a 30-06. I don't see too much sense in UNDERloading a round either. I'm also not so sure there's that great a difference in the killing power of one starting at 2600fps vs 2700fps. I don't mind pushing the envelope a little but ya gotta stop somewhere!..........................dj
