8mm-06 load data

Thanks guys good to know! I think I’m on the right path with CFE223… I’m going back to the range this pm and I’ll try 2 more loads, 59 and 60 grains of the stuff and see what I get in terms of pressure signs if I get any! I’m hopping to get 2800fps with the 200gn bullets! Even at 60gn there is still quite a bit of room in the case, so not compress yet!
I’ll repost back!
 
QuickLOAD shows your 58 grains at 2734 muzzle (3320 ft/lb energy), which seems to match your chrono in post 15 with calculated 94.9% fill

With the default max pressure of 58740 the 58 grains is just above that (58589).

FWIW
59gr is 96.6% fill, 62004 pressure, 2779fps and 3430ft-lbs
60gr is 98.2% fill, 65611 pressure, 2824fps and 3541ft-lbs

Cartridge          : 8 mm-06
Bullet             : .323, 200, Speer SP 2285

I don't have the data here, but I've smoked a few whitetail with an old milsurp sporter 98 with 150 grain Sierra pointed soft point and a dose of Higginson 47SB. Never got a chance to ask the deer about velocity, but I have put the old rifle on paper and it is accurate enough to suit me.
 
Paul T's post is very informative and from those numbers, the pressures are rated in pounds per square inch, rather than piezo units.

Mauser actions were proof-tested with special cartridges producing appx 65,000 pounds per sq in of pressure.

That is the MAXIMUM pressure the rifle was guaranteed to handle, the very odd time, not as a steady diet, nor even close to it.

This doesn't mean there will be a Kaboom, but it does indicate parts will be over stressed and damage might be the result. At the pressures you're loading to, I would definitely check for lug set-back recesses on the locking faces inside the action.

I've had to scrap more than one receiver because of such issues.

You might get lucky for awhile, but it's likely a matter of when instead of if, before this happens.

98 actions are tough. There are all sorts of horror stories of early types coming apart or late war manufacture not being heat treated or made with inferior materials.

I've had one 98 Kaboom and that had nothing to do with over book pressure loads.

It was a lovely sporter, built on a pre WWI GEW98 action, etc. It had been softened to enable hand engraving and when or if it was reheat treated, it likely wasn't done properly. The load used was only in the 45,000 psi range, with .318 diameter bullets.

Be careful. You've done very well to this point, Good luck after this point.

Maybe guntech, tiriaq, or Leeper would be gracious enough to give their view on this.
 
I was just out at the range with my inherited 8mm-06 with a 200gr PSP and 49.5grs of D4064. There were no pressure signs, I will chronograph next time I go out. Love seeing posts and load data that pertain to this cartridge.

Newer commercial 98 type actions are rated higher than this, but with older stuff I would be cautious as well. - dan
 
The only thing that changes when I increased max case capacity to 71 and COAL to 3.284 was the 58 grain load moving into the Near Max range from Over (still based on 58740 psi). Slight drop in velocities

An other day at the range with the 8mm-06 hand reamed old mauser 98, I settle on 58gn of CFE223 behind 200gn speer hot-cor, 30-06 norma brass, fed 215 primers! Velocity is around 2745fps that is over 3340ftlbs at the muzzle!
Link to my 4 shots groups, top one at 50m(1.20”) and second one at 100m(1.40”) open sights!

So for people telling me it wasn’t worth it I say it was totally worth it and the rifle cost me $350 all in!!

Good shooting! I'm happy with my 8mm-06. I'm shooting 200gr NAB at 2800 fps for about 1 inch groups.

What are you using for components, brass, powder, primers, coal?

Cant remember off the top of my head but I'm using 30-06 Winchester brass, RE17 powder, fed LR primer. Shooting a Zastava Mauser 98.
