There's really no need to build a 200 yard fort, DD. We are NOT building anything that big and we doubt that anyone will build what Artilleryman was writing about, that half-scale 100 Pdr. Parrott. What we do need to know, however, is what bore size defines the "medium guns" which would fire at 100 yards that you mentioned in Reply #36. I have a $20 bet with Gary that you won't be allowing anything over 1.75" diameter to fire at the 100 yard fort. You are going to cost me serious money if you say 2.25" or "anything under 3.00 inches", so please be as steady and predictable as you normally are. Say 1.75". Thank you. If someone really builds something BIG, Mike and I will show up a few days early and help you build and transport the 200 yard fort.
Another reason we have re-thought the larger, solid-shot gun is Safety. After the Myth Busters House piercing episode, we got to thinking about all that smooth, rounded river rock the range has and decided to err on the side of safety and go with a smaller, lighter, solid shot, so that if a ricochet does occur, the projectile will not carry nearly as far. We don't give a hoot as to how much insurance the club carries, we simply will not take ANY chances with our cannon shooting. In the Civil War there are plenty of instances of solid shot going off in unpredictable directions after hitting gun tubes, iron carriage parts or rocks. Zinc is much softer than iron or steel and less likely to display this behavior and will be used by us when a bore size is decided on.
