I recently bought some military 308 primed brass. I'm guessing the primer is corrosive. I'm wondering if I have to increase/decrease my normal loads (I use start grain)?
 
Some military primers are corrosive, a great many are not. What is the headstamp on the brass, perhaps someone here can say?

You won't have to change your loading practice due to corrosive/noncorrosive primers.

Being military brass, it may well have smaller internal case capacity than most commercial brass. if you are using .308 military brass that weights 185-195 grains, you typically you need to decrease powder charges by 1-2 grains from what you'd use in 160-170 grain commercial .308 brass.
 
Why would military 762x51 have corrosive primers? The vast majority of military 762x51 does not use corrosive primers. The only stuff that might would come from eastern European countries.

Any primed military brass has likely been once fired stuff that has been reprocessed and primed so those are likely civilian primers.
 
I'll take a look at the headstamp when I get home from work.... I bought the brass from a gun show and the guy said it is unfired military brass, he removed the bullet and power.
 
Ok I can't remember my photobucket password so I couldn't up load a pic. But the headstamp has IVI 71 on it. I google it, seems to be Canadian.
 
iF IT IS ivi IT IS CANADIAN AND IS GOOD BRASS I HAVE A COUPLE THOUSAND OF THEM THAT I USE IF IT IS UNFIRED YOU WILL HAVE TO REMOVE PRIMER CRIMP AFTER YOU FIRE IT SO YOU CAN RELOAD IT
 
If it is IVI .308 brass:
- it is noncorrosive
- it is boxer-primed
- it is standard Canadian military ammo. "IVI" is "Industrie Valcartier Industries"
- it is good strong brass; not match grade, but it is certainly more than good enough for nearly all uses.
- it weighs 185-195 grains - reduce your loads 1-2 grains vs. standard commercial brass
- the primer pocket is crimped; if you reload them, you'll need to de-crimp the primer pockets
 
Buy a Dillon Super Swage 600. I've bought and tries just about everyrthing for crimp removal. After it was all said and done I ended up buying the Dillon.
