H450 30-06 data? Anyone?

Using a known happy seating depth I was pushing 180 SSTs out of my Enfield at 2450 fps and shooting 1/2 MOA consistently today. Still have 4 pounds to play with.
 
59.0 grains which was my max was about an inch at 2654 fps and kicked like a mule!

1970 Lyman manual lists 56.5 as max H450 180gr .30-06.
2724fps from their 26" test barrel.

So, at 59gr, you're a "bit off the map". Every gun is different, but if there's no bevel on the edge of the primers, you shouldn't go any higher!! And would probably be a good idea to back off your max a little, too.
 
I have Nosler 1st manual and they use H-205, H-450,H-870 also Norma MRP. I used MRP 7mag and H-870 7 Wby. For 30-06 they used H-205, 280,300H&H and some others H-450.

Propellant Profiles 2nd Edition had max of 59gr/H-450,180gr @ 2604fps listed for 30-06. The loads go from 220 Swift to 460 Wby and they list cost @ $3.25 per lb can.

My old Hodgdon data pamphlet that came with the powder said 58 2581 46,000
My even older Lyman - 1967 had 54 to 60 grains
1964 Speer said Max was 62

I know these were all old manuals. I did work up slowly and I did back my maximum off. I actually like the 2450 fps just fine and it didn't give me bruises. Between all of the manuals I read there was a 6 grain difference in max load!

I will say that the process I used seemed to be pretty effective at finding a nice sweet spot. So far it is the most accurate powder I have for the 180 grain bullet in my Enfield.
 
Yikes!!!
A pound of powder to find a load??

I use a total of 22 shots. That includes ladder test and group test to find seating depth.
 
You did in post #15.

" On average it takes me a 1/2 to a pound of powder to figure out a decent load"

Wanna talk variables...
I load for 9 different people. 25 different rifles. 10 different cartridges( 223, 30-06 etc).
6 different bullet manufactures. 5 different powder manufactures ( Hodgdon, IMR, Win counted as 1). And bullet weights ranging from 35gr to 210gr.

Makes my own head hurt thinking about it. :rolleyes:

That doesn't take my pistol loading into account.

Ok. I would love to know your method. If i can make 1/2 moa ammo for my gun in 22 rounds that would be spiffy. I guess part of my way is to gather data along the way. But when i make 10 identicle rounds shoot a 2 inch group who is to say what 10 diffetent rounds will tell me. The randomness makes me question what i am seeing.
 
The randomness is always there, but it becomes a less likely influence as groups become bigger. For a five-shot group 19 out of 20 groups will be about -40% to +150% of the average five-shot group size you would get for an infinite number of groups. For a ten-shot group, it's about -20% and +23%. For 25 shots it's about -9% and +10%.
