To check the volume without measuring tools fill it full of alcohol and pour it into a commercial case. Alcohol doesn't have the surface tension water does and will lay flat.
Questions about .308 LC 67 Match brass
Am working up 308 loads for my brother and his boys. Have been using Remington brass and about got the load worked out, and then my brother brings me about 250 of these LC 67 Match brass from his father in law. Looks like once-fired, but can't be sure. (Hoping it wasn't fired in a machine gun.) Questions...
Is this a thick-walled brass with significantly reduced capacity compared to the Rem brass?
If so, any recommendations how far to back off the powder charge from my existing loads?
Roughly how many loads I can get out of these brass?
Any other quirks to this brass I should know about?
For reference, my current load is 46.3-gr Varget, Rem 150-gr core-lokt, Rem brass, CCI primer. Thanks in advance for any advice.

I'd put a spent primer in for the test. If all you have is a live primer I'd fire it afterwards rather than risk depriming a live primer. I guess you could also jam a toothpick in the flash hole as long as the same amount protrudes into the case. Both need to be sized or both fired from the same chamber.smoffett said:I like that idea, but I think the alcohol would flow out through the flash hole unless I plug it up. Maybe I could seat a primer in there for that? Would that be safe? Could I deprime it afterwards without the primer blowing up?PhillipM said:To check the volume without measuring tools fill it full of alcohol and pour it into a commercial case.

I found a better way to do it from another forum.

see post #6This is done by seating a bullet without a primer or powder, weighing it with a piece of scotch tape across the base, then filling the case with water via a hypodermic syringe to the top of the flash hole and replacing the tape then weighing it again. The difference is water capacity. Without this figure, you are going at it blind. You will be amazed at the variations between cases. And, since we have no way of measuring pressures, proceed slowly.
