    Handgun Stopping Power? LOL NO! Bump It Up A Notch Or Two!

    Attachment 290693

    26-inch thick armor from a Japanese Yamato class battleship, pierced by a US Navy 16-inch gun. The armor is on display at the US Navy Museum.
    Got a .22 .30 .32 .357 .38 .40 .41 .44 .45 .480 or .500 S&W cylinder that needs throats honed? 9mm, 10mm/40S&W, 45 ACP pistol barrel that won't "plunk" your handloads? 480 Ruger or 475 Linebaugh cylinder that needs the "step" reamed to 6° 30min chamfer?

    Ok but if the magazine doesn't hold 17 or more rounds it's worthless.
    On the other hand if it can fire more than one round it's an "assault weapon" and should be confiscated.

    Aw, com'on, Doug. That's hardly a handgun! Those pics sure are impressive, though, aren't they? A shell the size of a VW bug going at speed will do a lot of damage.

    Not to pick bones with you Wayne but it's the weight of a VW Bug not the same size. We need a heck of a catapult for that.

    Nice target shooting Dougguy. How much labor time is charged to throat that barrel to shoot cast boolets?

    Can we get a picture of the shoulder rig for that gun?
    Paper targets aren't your friends. They won't lie for you and they don't care if your feelings get hurt.

    If we are picking bones, then it has the same mass, not weight. as weight is a product of gravity, mass is a constant. so a vw bug weight is less if it is on the moon, but the mass is the same.

    A link to the story behind that photo: http://www.byronhartshorn.com/2014/0...ship-showdown/

    A photo from the other extreme: This is the impact crater from a Japanese 5" equivalent on one of the U.S.S. Iowa's turrets

    I'm guessing that photo was taken before conservation efforts got underway at Iowa's current museum berth in San Pedro. The hole has a fresh coat of gray paint over it and it looks more like a casting/forging flaw or rust pit than battle damage. You'd barely notice if not for the yellow arrow and tour guide plaque.

    But the funniest bit:

    I'm reasonably confident a 16" HE round would cause "reproductive harm".

    Can't imagine what that did inside the vessel.

    Lets see if I remember the stats right or not.

    Weight of projectile: 16"/50 cal AP is 2,700 lbs.
    Initial Velocity: Not sure but 2,600-2,650 fps was fairly standard for naval gunnery. (It varies according to temperature.)

    I do know the FC's used the last three days powder magazine temps to figure IV for our 5"/54.

    MG you forgot the BC advantage of something like 5 or 6 .

    The 16" Howie on the Iowa , 1 of which I got to fondle before a slab was cut off for a little museum out in the Nevada desert , had an 80 mile range . 10-20,000 yd was chip shot ranges on standing targets .

    An electronics guy that did part of the last generation targeting gear on the Iowa told me that with the Rocket Assisted projectiles they could shot 105 miles and keep the shells inside a football field grid per turret . Can you imagine ? That's the same as "a little vertical stringing but I can still cover 3 with a half dollar at 1000 yd" ...... Lots of electronics and drive motors involved . He also told me that a top gun crew in WWII could do the same consistently but only at 50 miles and they used the whole stadium . In any case it was a fair bit of shooting .

    That would absolutely ruin the hide and meat.
    The solid soft lead bullet is undoubtably the best and most satisfactory expanding bullet that has ever been designed. It invariably mushrooms perfectly, and never breaks up. With the metal base that is essential for velocities of 2000 f.s. and upwards to protect the naked base, these metal-based soft lead bullets are splendid.

    I seriously doubt you could shoot cast in one of those 16 inchers. Cast and machined bronze maybe, but anything softer would just slug up upon firing, the base of the boolit would be moving before the nose moves, prolly make a helluva pressure spike, and I bet you could bulge one of those barrels if you tried!

    I wonder how much freejump there is in there before the shell engages rifling?
