I thought it would be fun to start a thread that everyone could participate in, so I pose this question... What is your Holy Grail of artillery projectiles? Assuming you could locate one to acquire, and money wasn't an issue, what is the ONE piece you would add to your collection right now? Or maybe you're even lucky enough to already own it.
I have to say for me I'm particularly fond of the 7in. James Bolt, and my collection won't seem complete until l I get one. So what is yours?
