Militry Brass or Commercial Brass

B9mmHP · September 16, 2000, 04:48 PM

If I remember right some one said Military Brass is thicker than Commercial/Civilan brass.
If it is what differance dose it make on reloading? More pressure? Should I keep them seperate.

Yes I would keep the brass seperate. With the military brass will have a higher pressure then a commercial brass with the same powder charge. Because of the case volume is smaller in most military. If you are at max load with commercial brass and then change to military brass you will be over pressure.

With military brass allways decrease your powder charge by 10 percent.It is a real good rule of thumb

Is that for both rifle and pistol caliber brass or just rifle brass?

I know pistol brass is thicker, I not sure about rifle brass. I have use only commercial brass for reloading rifle.

A good rule of "thumb". Drop the load back 10% for Mil Spec brass. You can work it back up from there. There is usually slightly less internal case capacity in Lake City brass than in commercial brass.
