I recently acquired a Marlin in 45-70. The older gentleman that I bought it from gave me some loaded ammo and empth brass with the gun. As I was leaving he remarked that "Some of the brass is older stuff and is balloon head, so dont load it too heavy." I didnt want to show my ignorance, so I did not ask for clarification, but I am not familiar with the term or the brass. I have never owned a 45-70 before, so this is new territory and I dont want to make a mistake.
So my questions are:
What is "balloon head" brass?
How is it different?
Is it safe to load?
Any help is appreciated!
Yes, I can spell. I just cant type!
