3006 Military and Commercial brass

[RoDog]

Are the inside dimensions the same as Military and commercial cases? With 308 Win and Military, they are different. Military has thicker cases, so you should lower the charge 1 or 2 grains because of less case capacity. Is this the same as 3006? Or use 3006 Springfield load data for both. Was thinking a water test.

Curious

308 Win is not a military caliber, 7.62x52 Nato is.
Different animals.

Yes, and when i use both cases, i keep the charges a grain or two lower than 308 Win. Just wondering if the inside

With the added case volume of the 30-06, i'm not certain that any slight increase/decrease in wall thickness is going to show up as much as the smaller volume cases.

I've loaded up some cases made in Greece in 1972 & some new Hornady cases. Didn't notice much, if any difference in case prep or shooting.

If MILITARY Brass is used, the charges shown should be reduced one to two grains (308). Thicker construction of MILITARY cases decreases capacity, making a reduction in charge a necessity. So, im wondering if its the same for 3006.

Nowhere is there any distinction between sporter and military brass for 30/06.
Go back and study the Wiki page linked earlier but with your reloading manual out for referencing velocities between Mil and hunting loads. Pretty plain to see lots of the Mil loads were pretty plain compared to modern hunting loads.
If in any doubt let the crony and reading primers tell the full story.

Your reloading manual or the on-line data sites will all give you a start load, with a given bullet weight, work from there, up slowly and watch for pressure signs and you will find a load for YOUR rifle and the cases used that is accurate and safe.
Either commercial or military brass will work.

^^^^^This!

distinction

Looks like you answered my question. I think they are the same.

The 30-03 and 30-06 were military originated cartridges going back to 1903 and 1906. The is no distinction between military and commercial. There are differences between different brass manufacturers but are not huge. The Military also developed the 308/7.62x51 and most commercial brass does not differ from military by any large amount. HOWEVER, Winchester refined the 308 case for Palma competition and that brass has a considerable increase in capacity over military due to the case/web design. That is where the major difference comes about.

Yes, I guess 308 and NATO are the only ones that are different inside. That's why 308 load data cant be used for NATO cases, UNLESS, you lower the charges one to two grains.

I have about 200 OLD 30-06 military cases from the 50's. I'm wondering if they will be OK to reload, because Ive heard stories about the old powder degrading the brass cases and making them brittle?

 

[Doug Casner]

I thought wall thickness was thicker on all military brass compared to sporting brass. Doug

I measured water capacity on some mil 7.62 ×63 brass recently. Weighed Winchester and RP also. Win had a good bit more, the RP and KA73 had similar case capacity surprisingly.

Yes. I'm asking if old brass could have been weaken by the old powder in old cases. It might be older cases, not sure.

My understanding is that back several decades ago the priming mixture of the day (era) contained mercury -Hg- and that was the agent that attacked the brass so your concerns are only valid if you have some pre WWII cartridges, as any fired ammo that had mercuric priming would not be a cartridge case anymore. The next evolution of primers caused damage to barrels and gas systems( but not the cartridge case) through a salty acid residue that was very cleanable but had to cleaned quickly or rust was inevitable. A lot of the corrosive primed stuff still around but mercuric based, not so much. Hope this helps! TexasC

I just did a water test on two cases, one PMC and one Old military from 1955. PMC case had 65.2gr, and the military had 65.7gr. I think ill be ok to reload them, I only have 100 or so. Ill keep the charges down too. Commercial case had less capacity too, weird.
