davidmurray I would venture the opinion that doubling the diameter, or radius if talking math of a shell, you would have to double the length to maintain ballistic performance. This would make a 16" shell eight times heavier than a 8". The old square cube rule in effect. Dave

Overmod >Now double the size to 16''inches, about the same range. No, it's much better than that. What you doubled was the diameter. The size went up four times. That's not a trivial difference!

dehusman I always suggest that people do their own research, rather than just ask questions on forums.

Not to dispute that, but sometimes you get personal experiences that are not online. Also there are some tidbits that are not online. (Certain railroad books are not posted online and where I am I don't have easy access to them.)
dehusman I have found out more cool stuff looking for other stuff than you can imagine.

On the other hand, I will admit I have found a few things via eBay (my online hobby shop) that I couldn't havve found anywhere else. Good examples: my car float and dock as well as the building that will be used as a station/resturant for my tourist railroad.
I won't have the big guns or big-gun carrying transport car on my layout, but a bunker for big shore defense guns is part of the prototype scene I am modeling in Galveston, Texas.
locoi1sa While doing some research for my F22 flat cars with the 16 inch gun load I came across Mr. Gene Slovers web site. There is where I found this very impressive picture. http://www.eugeneleeslover.com/AMMUNITION/USS-IOWA-BROADSIDE-FIREING.html Those guns were powerful! Research is fun and one can easily be side tracked. Pete

By the way one Google research resource that too few know about is the Google News archives. It is not always easy to get into but for certain types of prototype research I have found it fascinating and helpful.

richg1998 dehusman I always suggest that people do their own research, rather than just ask questions on forums. I have found out more cool stuff looking for other stuff than you can imagine. I have suggested Google searches here in the past. The Ranters went ballistic. Rarely is anything, Ungoogleable. Some here like a following they have and don't like people searching on their own. I have built extensive links on modeling in different subjects. Much better than being led by the hand with a sense of accomplishment. Rich

Rich, Dave... I completely agree with both of you. The search is an adventure and it leads to some pretty amazing places. The <right click/save picture as> will also let you amass a personal collection of photos and diagrams for future reference, too.
Shorpy, Wikipedia, Google and the hundreds of historical societies and photo collections can reveal a wealth of information for the curious researcher!

If you ever fall over in public, pick yourself up and say “sorry it’s been a while since I inhabited a body.” And just walk away.

I have the same resin kits too. There was an F22 brass painted with load bolster on evil bay that I was going to bid on. It went for $90 plus shipping. Not bad but too steep for me. I have the AMB wood decks and gun kit. I also picked up two sets of HD arch bar trucks with the three visible coil springs.
Thanks to all the other responders too. Been there with the M109 and M110 Howitzers firing. The cuncusion was big from them. I can't imagine the 2500lb 16 inch shell. Looking at the depresion in the ocean is what caught my eye. WOW, what power.
I pray every day I break even, Cause I can really use the money!
I started with nothing and still have most of it left!
http://www.usscolorado.org/index.htm
is a magnificent website devoted to the USS Colorado (30 pages of great photos) and a complete summary of its service record. It took a pounding during WWII but gave as good as it got particularly at Okinawa.
The website notes the remaining artifacts of the Colorado but no mention of this continuing use of its 16 inchers. Someone might like to be informed that this part of its past is still in use.
Having experienced first hand as a forward observer, the guy that calls the shots, so to speak. You do not want to be any where near, where a shell hits. Vietnam, IFFV HDqtr's Btry 6th BN 32nd 8'' inch self propelled ARTY. No one is safe, for a radius of 50ft when a phosphorus shell goes off, let alone the impact. From 17 miles away. Those howitzers were the most accurate for the time. Now double the size to 16''inches, about the same range.
DAVE H, Knowledge is light, in my books. Plus I like to read. And the search, is part of the adventure, which seem's to be lacking, now a days.

Thats all very nice and well Dave, BUT I get can get too easily sidetracked.
Cheers, the Bear.
P.S. Interesting photos , I've only been close up to an existing WW2 battery of two 6 inch guns in Fiji, and thought they were big enough.
"One difference between pessimists and optimists is that while pessimists are more often right, optimists have far more fun."
I have been on the receiving end of RPG's, Mortars, rifle rounds, and light artillery, etc.
But can only imagine the destruction of being on the receiving end of a 16" gun shell.

Hi, Pete
I share your interest in the 16" guns and I too have looked at Eugene's site. My workplace happens to have a pair of 16 inchers off the USS Colorado (BB-45) and I see them every day.
Here they are in 1958 being readied for their trip to Ohio. I believe this photo was taken at the Watervliet Arsenal.
Thats F22 PRR 435390 in the photo! Must have been part of a public display? Machine guns at the ready to keep the folks from getting out of hand...
And, after shortening, arriving in Ohio June 1959
That would make an interesting load in itself! Look at that blocking. If the gun don't fit the gon, cut her down!
And here's how the gun looks today... well, yesterday! With the muzzle end cut off and plugged it is used as a 40,000 psi pressure vessel for sintering metal powders.
I'm working on some resin F22s and I know the minute I get them finished Bowser or somone (Tichy would be nice!)will make them available in plastic! That's the breaks!
Take care, Ed
Research can also come up with some amazing facts - like the fact that one wife of a past Norfolk & Western president had a chair fastened to the pilot deck so she could get an uninterrupted view of the oncoming track and scenery. (Unfortunately, it was found in a book devoted to shady financing and boardroom shenanigans, with nary a mention of routes, track arrangements or rolling stock design.)
I know how easy it is to pull up a Wiki and then start prowling through all the blue words just to see what crawls out from under a rock. Or to inquire on one person's name, only to find out something about an entirely different person and the connection between the two. History is vast and complex - and fascinating.
